Trying to add another BLE service besides the keyboard service

[renederidder]

I have an ESP32 that works very well acting as a BLE keyboard for an app running on an Android tablet. Now I need this ESP32 to act simultaneously as a BLE server with a custom service to another ESP32 acting as client.

So after the bleKeyboard.begin(); I can add pServer2 = BLEDevice::createServer(); to create the server for that custom service, and the keyboard still works fine.

But as soon as I add the line pService2 = pServer2->createService(SERVICE_UUID); the keyboard stops sending keystrokes.

Why would this added line break the BLE keyboard service?

Unfortunately I don't know enough about the BLE libraries to answer your question. Maybe the people who wrote those libraries can help. The BLE libraries are only OOP wrappers around the official function based API btw. So you can look at the source code of those libraries and try to figure it out that way. The official API is way better documented and it is way easier to get support for that.

Someone got idea how to fix it?
