Hi Chris, thank you so much for this tutorial. I have been struggling with various Arduino libraries for the E220 module, running on both ESP32 and Wemos D1 mini. Non of them worked but to my amazement your simple approach worked first time. Now to find out what range I can get! Thank you again👍
It's 22dbm of transmit power (156 milliwatts) and with that antenna at VA Beach it worked at 8 miles which is the maximum length of that beach from the breakwater on the south end to its northern extremity.
My guess would be no as the signal from the arduino TX pin is 5V so this is why the voltage divider is used. I have had to do this with an SD card slot which has to have 3.3V for the MOSI, CS and SCK pins. the MISO pin doesn't though as it is putting out 3.3v to the Arduino which isn't an issue. The only thing i would do differently with this tutorial would be to put a 1k resistor in series with the receiver and lora module to limit current.
Great video. Thanks. I wanted to learn Lora programming so I purchased two. I received this model e220-900t22d and e220-400t22d. Which one is the transmitter and which one is the receiver?!!
Unfortunately, these are two different radio modules meant for different frequency bands, "400" and "900". If you're in the US, you'll want another 900 radio to complete your link.
Thanks a lot for your reply. I am just learning this stuff from tutorials yours. Which is better, though? The Chinese would sell you anything, wouldn't they? Thanks again@@MissionSuccessGo
@@mingosutu It's not so much which is better, but rather which is legal in your country. In the US, the 400mhz band is regulated, and so not allowed to be used for civilian general comms, but 915Mhz is. Using the incorrect frequency can get you in trouble--fines and such, usually. I'd do a little research on your end to understand what frequency you're allowed to use. You'll need a matching antenna, and perform the UART to USB connection with the EBYTE configuration software tool as shown in this video to configure each of your radios.
Chris, great video. Have you done done your testing and / or installation for the SCADA yet? Also, are there security concerns, or is the signal encrypted in some way? I would love to see more LoRa vids.
Hello , yes it should , the only difference between a 900m22s and the one used in Chris's video is the type of antenna connection . both are e220 modules.
Hey , i am sorry i didn't pay attention to the M in there . 900 M 22 s . i checked the manual , from a first glance that is an SPI module . not a UART module like the one in this video.
Incredible tutorial, thank you! This gave me exactly what I was looking for to help with my project. I love your schematics!! Incredibly helpful!
Chris, thank you for your time.

Amazing. Great Job.. 👍
amazing job. Thank you.

sounds good thanks
Hi, If you power the E220 with the 3.3V from the arduino, could you then remove the pulldown resistor at 4:27?

For a Gateway (LoRa plus WiFi/MQTT),
is there an as simple way available to
specify the serial read/write?
thankyou chris, your video so helpful ,can i request about lora E220-900T30D connect to esp32 dan dimmer , i hope you can help me

SCADA is working good. I didn't feel the need to encrypt it.
Thanks
I want to work with lora e220 throgh attiny841 can you help me ???
Give solution work with arduino or microchip studio??
Would this work for e220 900m22s?

@@mkivcromwell5323 i got the spi working. I can send receive cmds to the micro. But broadcast isn't working.
nice thx
