BLEwrite Example -> onWrite not working #1168

Open JanB97 opened 12 months ago

JanB97 commented 12 months ago

So I've been banging my head against a wall and don't understand the problem here. If been trying the Write and the UART example but on both the onWrite even is not fired after writing something to the characteristic via the nRF_Connect App. onRead does work on both.

Can someone guide me what I need to change in the examples to make it work? I am using a Lolin D32.

This is what I get from the Verbose Debugging on the ESP.. It does recognize if I send something, but the funktion never get's executed.

Okay so I tested it with a new Heltec Lora ESP32 V3. With this board it works, it has a ESP32S3. I am still interested why it is not working on the Lolin D32 Board.

I'm struggling with the same issue. The onWrite callback doesn't work on my Seeed Xiao ESP32-C3 board, but it's working fine on Seeed Xiao ESP32-S3.

I am having a similar issue using a Waveshare ESP32-S3 mini. When I run the BLEwrite Example the onWrite event is never triggered on Platformio (Ubuntu). But when I run it on Arduino IDE (Windows) with the same code it is working fine.

As the Waveshare board is not on the platform I am using lolin_s3_mini with below ini file.
