Hey, please comment about any content you would like to see.
when i start scaning its all time dosnt show any device
471 views and ive probably been 30-40 of them ive just now got the basic of turning the led on and off after working on it for 7-8hrs this week... GREAT TUTORIAL
Haha, it's appreciated
Thank you so much for making this! It was very useful for my Final Year Project in University!
Good job buddy. You've got a good way of explaining! Keep it up.
Thanks, you too!
This is exactly what i was looking to do. Thanks for the Tutorial
Thank you! This was super helpful and got me started with my University project nicely. If you could make a video explaining how to receive data with AppInventor that would be great!
I wish I could make a video, but unfortunately I am unable to figure it out myself.
Thanks a lot 🙏🏻
No problem, what videos are you most interested in seeing?
Hi, where did you find the full service and characteristic UUID?
can you tell me how to send data like voltage measured from arduino to ble hm-10 connected to an app.i am not able to get the data in the app created in mit app inventor.i am using read strings.but no strings are displayed.
please help me with it
Unfortunately I am not able to. I have tried a similar thing myself with no luck. I am quite sorry, but if you have any other simple arduino projects you want me to do please comment.
@@oddladout4076 i am making a project on arduino.water level indicator. its show 0%, 25%, 50%, 75% and 100% water level. but the level should be displayed on the android app made using mit app inventor.
board:arduino uno or esp32
bluetooth module for arduino : hm 10
please help with it bro
i am facing difficulty in sending data to mobile
Let us say you are using the Battery level example and want to assign the readings to a label. You want to send the battery level readings across from Arduino to the mobile app. It's hard to type the blocks out to make it understandable but what follows would be my best attempt to make it as simple as possible. B1 (when device.connected> registerForBytes: Plug in proper UUIDs for service and characterstics. "Signed:false)B1. B2(when bytesReceived>set LabelText: getByteValues)B2. It is a good practice to reset the connection with companion app each time you alter the blocks because at times it appears to be frozen and not show effect of the changes made. Hope this helps.

Hey Qwerk Werx, I have a few questions I am praying you are able to answer because I am stuck on my project.
Receiving byte data like "1" or "230" to turn the LED on works perfect. But how would i send, for example byte "33", back to the app after a set amount of time from the arduino (delay(5000)) for something like:
App:
When recieved data == byte 33 then make jpeg. Visible.
I hope you can help.
The main thing I want now is just to be able to receive the same type of byte back to the app.
Huge thanks, your video already helped me a lot.
Ahhhh, unfortunately I think I’ve tried something similar with sending information back to the app. I really wish I could help. If you find the answer please let me know and I’ll try to make a video about it.
Hi, where is the .aia file?
Can i use the same service and characterristic uuid on any device or does it vary?
Excellent question. I’m sorry I can’t answer the question. I’d say your best bet is to try it and find out. Sadly college has a way of reducing the access I have to my tech toys😢
Can we use Bluetooth 4?
Can you please add a link to get to ur aix file. Thank you
Sure, I’ll set a reminder. I just hope I can find my AIX file.
@@oddladout4076 I would also appreciate an AIX file. Thanks for the video!
I will try to look tomorrow, I hope I can still find it. Sorry for the delay, I’ve been extremely busy as of late.
