hi i also using ths same zigbee but the length of transmit and receive signal less than 1 meter more than that signal will lost can help me to get the range as in data sheet
Hello there :-) I'm sorry for the delay in my reply, but I didn't get notified about your comment. Only one meter?!? Were your antennas pointing towards each other? I got a further distance than you, especially when my antennas were pointing towards each other. After all, the antenna on this ZigBee module is directional, not omni-directional. Kindest Regards :-)
Ando trabajando con estas antenas, he logrado prender un led pero no se donde podria moverle, para hacer una secuencia de leds como la que muestras el final, trabajo con el pic18lf4620 y con MPLAB no se si puedas ayudarme?
Hello there :-) I'm sorry, but I'm not familiar with PIC18LF4620. I'd suggest that you change your MCU to PIC18F45K22 instead, and try to make the program work, then you should make the necessary changes in order to make it work with PIC18LF4620 later. Best Regards
Hi which ZigBee stack you are using ? I came to know that you have to use Microchip provided stack with microchip provided compiler. And microchip ZigBee PRO stack costs 995$ ! Is there any free stack available ?
Krishanu Banerjee Banerjee Hello and thank you so much for watching my video :-)I've never thought the stack would cost that much! That price is unbelievable! In this video, the used stack is the one that (MikroElektronika) put in this example. After all, I didn't write the code for this one from scratch, I simply showed their example in the video. The stack didn't cost me anything. But I have just checked the datasheets of (MRF24J40MA) and (MRF24J40), they both say: "The MRF24J40 is compatible with MicroChip's ZigBee, MiWi, and MiWi P2P software stacks. Each software stack is available as a free download, including source code" From where did you get that price information? Or did I misunderstand you? If so, then please clarify your question. Best Regards :-)

Mohanad Ghazi I think I looked at ZigBee PRO stack
Krishanu Banerjee Hello again :-) I looked at the link which you sent, and it seems like a more advanced version of the stack, so that explains why it's not free. I didn't quite help, but please let me know if you needed anything else. Again, thanks for watching my video :-) Best Regards
Mohanad Ghazi thanks man. I think I am clear now.
please how i can connect MRF24J40MA to web browser please i need help
Hello Walid Msilini and thank you so much for watching my video :-) In order to do that, you'll need a Wi-Fi module as well as the MRF24J40MA since the ZigBee module cannot connect to the Web Browser by its self. Maybe you should consider using Wi-Fi instead of ZigBee in order to reach your goal. Well, this is the best advice I can give you at the moment. I can try to help you out further if you could give me additional information. I wish you the best of luck! Best Regards :-)
Hi Mohanad, That was an interesting video you prepared. I am trying to work with MRF24j40MA . I couldn't find any notifiable source to follow my goal and the datasheet isn't clear enough in my opinion. and I do appreciate if you could feed me with your sample code. here is my email address: sepehr_saadatmand@yahoo.com
Thank you so much for watching my video Sepehr Saadatmand :-) The sample codes for both of the PICs are those of the example that the (Mikroelektronika) team posted on (LibStock). Link to the sample code: www.libstock.com/projects/view/242/bee-click-example You can download it from there, and further more, you'll find the same sample codes for running this example on different MCU platforms! Please let me know if you needed anything else :-) Best Regards.
Thank you for your video. What is the minimum pins I can use in the MRF24J40MA to have P2P communication Thanks
Hello Manie de Bruin and thank you so much for watching my video :-) WOW! This is quite an interesting question! And a tough one too! Short answer? I think it's three Long answer? There you go: To list its pins in order of importance in my point of view: 1- One is used for data from the MCU to the MRF24J40MA. 2- One is used for data from the MRF24J40MA to the MCU. 3- One is used to synchronize the data transfer time in order to ensure reliable communication. 4- One is used to wake up the module when data is to be transmitted. 5- One is used to interrupt the MCU when data is received. 6- One is used to reset the MRF24J40MA when needed. 7- One is used as a Chip Select (CS) pin. Of course, I don't think all these pins are needed in minimum, but only the first three, but I'm not sure though. I think you can include something in your circuit that saves you the MCU I/O lines that are connected to the rest of the pins. For example, the MCU I/O line that is connected to the Chip Select (CS) pin can probably be saved by using a simple wire connected to either the ground or the Vcc according to if it's active low or active high (Active low in this case), and so on for the other pins. I hope this helped :-) Best Regards
Hello! My question is how do you link two MRF24J40MA moduls together? Can I do the network of 5 or more moduls? Is the recivinv and transmiting transparent or not? With that I mean if I transmit a data, would it be recieved on all MRF24J40MA or not? Thank you for answers Ales Zupanc
Hello Ales Zupanc and thank you for watching my video :-) The modules are linked by a number of steps, where in the beginning, the coordinator node establishes the network and set the required parameters, then the other nodes join the network where they should have the same parameters that are requested by the coordinator. Of course, you can do a network of five nodes or more, but I gotta be honest here, I think it will be very tricky; however, I'm sure that you'll get all the help that you need if you posted the issues that you encounter in the MikroElektronika forum. Lots of nice people there :-) The transmitted data will be seen by only the intended receiver. However, if you sent a broadcast message, then all nodes will receive the message. Please let me know if I misunderstood you or if you had any more questions :-) Best Regards
hello dear I wanna set up registers with another micro (stm32f107rc) . and whould you help me set up necessory registers for example register X=0xff thank U
Hello Morteza Keikhaei and thank you so much for watching my video :-) Unfortunately, I'm afraid that I cannot help you with your issue since I have absolutely no experience when it comes to STM microcontrollers. I'd like to recommend that you ask your question either in the STM forum, or the Microchip forum. MikroElektronika's forum is a great place as well. I learn a lot of things there. I hope that your problem gets solved Best Wishes and Best Regards :-)
I am interesting to do a communication with Zigbee protocol; I'm using two antennas RMF24J40MA, I need that this just have communication between this, the question is: This project works perfectly with pic's or I could need a pic18 explorer board by microchip for can do this? Thank you
Hello Alejandra Marquez :-) I believe that this project can be done by any microcontroller as long as the chosen microcontroller can perform SPI (Serial Peripheral Interface) communication. That's because the MRF24J40MA can only communicate with the connected microcontroller through SPI. So to answer your question, this project works perfectly with PIC18F45K22, and it should work perfectly as well with the (PIC18 Explorer board). I've checked that board, and it looks like it's quite a powerful board. I wish you great luck with your project :-) Best Wishes and Best Regards
awesome , very good work , ... how long the distance between the receiver and transmitter ? are there a different band of distances in this product ? its compatible with Arduio ?
Thanks a lot for your kind words Laith :-) I'm sorry about the late reply. I've had lots of internet problems these days. As for your questions, the maximum distance between the Transmitter and the Receiver is 400 ft., that is according to the most recent datasheet of the MRF24J40MA (Datasheet is linked below), which is the Zigbee module on top of the Bee Click. You can check this in the third page: ww1.microchip.com/downloads/en/DeviceDoc/70329b.pdf Keep in mind that this maximum distance can only be achieved if the antennas are pointing towards each other (Directional antennas, not omnidirectional). I didn't quite understand your second question, but if it's about the bandwidth, then the answer is that this module works in the 2.4 GHz band, which is also called the ISM (Industrial, Scientific and Medical) band, and it has a data-rate of 250 Kbps. as for compatibility with Arduino, I think this depends on your Arduino board in use. You should use an Arduino board which has an internal SPI (Serial Peripheral Interface) module to make it communicate with the Bee Click. I'm sorry, but I'm not sure of which Arduino boards have this internal module and which don't. Best Wishes and Best Regards :-)
thank you mohaned for your video can you help me to make the same schematic with Isis because i cant found the "mrf24j40ma" in the isis library
You're most welcome Hamza :-) I'm sorry, but I'm afraid that I cant help you with your issue. I don't know much about (Isis) simulator, so I don't know if the (MRF24J40MA) ZigBee module is available in its libraries or not. I usually test most (If not all) of the codes of (MikroElektronika) compilers in real hardware because their compilers aren't fully supported by any simulator. Even the simulators which do support some functions of their compilers aren't considered reliable because they don't support all of the new compiler libraries, so they might give wrong results . I'd like to recommend that you ask your question to either the technical support of (Isis), or a forum like the (MikroElektronika) forum. I'm pretty sure you'll get better answers. Best Regards :-)
maximum possible distance?
Hello Pachipachi :-). It's 400 ft. according to the most recent datasheet of the MRF24J40MA, which is the module that is placed on top of the Bee Click. It is mentioned in page (3) in the following document: ww1.microchip.com/downloads/en/DeviceDoc/70329b.pdf However, keep in mind that maximum range can only be reached when the antennas are pointing towards each other (Directional antenna, not omni-directional). The worst case is when the antennas are put side by side. I wouldn't expect a range more than 100 ft. at that case. Haven't tried it though. I hope this was helpful. Best Regards :-) Note: When I checked the distance in the datasheet for you, I found it is 400 ft., but it says 400 meters in the datasheet which I downloaded some time ago. I guess it had been updated.
Thank you so much for your kind comment Maximiliano! I think you did all of the hard work, which is to change the code in order to work with PIC16F886. That's a great work! Best Regards :-)
Mohanad i wanted to thank you a lot for post a video with your modules working !! very good job , i just move the code and adjust some lines in order to work with the 16f886 pic and it worked at once !! thanks again buddy !! regards from Argentina !
Thanks. This is old. Today, the Rx. is displaying LED's based on push buttons on the Tx. and it will do harder tasks very soon. If I uploaded other videos, I'll make them interesting to watch, and definitely without showing my feet. XD Thanks again. :-)
Excellent display. Good use of relatively cheap components...ie without EZpic7 etc etc. A++
No, I haven't. I suggest that you read the example (the .Hex file) that the Mikroelekronika's team posted on LibStock.com regarding the BeeClick to learn how these transceivers are controlled. Reading the datasheet of MRF24J40MA and MRF24J40 might be helpful. As a PIC user, I found their (Ready for PIC board) quite a great platform for learning. Therefore, I suggest that you check their (Ready for AVR board). It might help you. That's all I can think of now. I hope it helped! :)
I plan to use AVR chips for these tranceivers. Have you ever seen such bundle? :)
Thank you so much for the kind comment. I hope that I implement more circuits with other click boards from Mikroelektronika, but I will need a lot of free time, which is something I don't have these days.
You gave us a good trust of entry this field by making this project easy to build with simple illustration ,thanks. Alhekma For Electronic Services
