Arduino WROOM32, bluetooth App. Editing characteristic values

Postby zombodotcom » Sun Mar 25, 2018 3:49 pm

I am trying to edit some values on an arduino program.

so I have a BLE for arduino setup like this
https://gist.github.com/zombodotcom/0b8 ... affd1570b7


I want to be able to access those UUID's it is generating ( it's the same every time even after reuploading for each as shown in the mage above).

I also tried my bluetooth app that I used for another BLE project but I can't seem to find a way to edit the individual characteristics, I can only access

Code: Select all

 6E400001-B5A3-F393-E0A9-E50E24DCCA9E
I have tried this in the BLE APP but it says it wont work or crashes when I add the pattern UUID.

Does anyone have any experience with this and a method they used that worked/ something I can read about changing the characteristics that the program gives me?

Also here is the github of the project

Hi,
seems you have problem with app inventor not with esp32, but i will try to help you. To resolve whole problem i would have to write whole book chapter, but instead i will give you app inventor example ive write which is handling few characteristics.
In this repository you have ota_app1.aia file:
