ESP32 with additional BLE-characteristics about esp32_ble_ota_arduino

[fbiego]

check this implementation of your code

main-ota.zip

[fbiego]

actually, I'm developing and testing a python script to enable uploads from a computer. I will post it when done

[fbiego]

Looks like you have not created SERVICE_UUID2 on the pServer
or if you are adding all characteristic to one service, the changes won't show until you refresh. I use the nRF connect app to refresh the services

[goosst]

Yeah, no real luck with or without that 2nd one ... .
I can see both service_UUID's (for a while at least, then it just disappears again untill a reboot of the ESP).
But I can't connect with the phone to upload a .bin file.

In case you're interested to have a look, I believe to have a minimal example. It sends a value to some characteristics and still implements your OTA method: main.zip
(using platformio but in arduino style ... so you can normally just leave out the #include <Arduino.h>, and save it as an .ino)

thanks!

[goosst]

Great stuff, thanks.
Getting it connected with the app and phone was a bit finicky, but at least it works once I got it connected 👍

By the way did you always do this flashing by phone or were there any ways to upload from computer?

[goosst]

I've tried again to integrate this example in my own code.
The best I get is a few % in the upload process in the app, afterwards the ESP just reboots. I'm using the .bin file from your repo as test upload.

Is there any debug information that is useful for this?
I'm about to give up on BLE-OTA.

[fbiego]

did you modify the main-ota code?

[goosst]

did you modify the main-ota code?

not the BLE parts: I've compared it a few times, I only changed the order of the function declaration. Latest code is here:

you may want to call your Receive() function in the NORMAL_MODE
