More info... I ran the GATT_SERVER and GATT_CLIENT on two ESP32 boards and they are communicating. The server didn't hang and stop responding when it recv'd the Read by Group GETT include declaration. It also responded with the Attribute not found response. That's the response that didn't go out as ...

More notes on this. This disconnect doesn't occur immediately. It occurs after about 7 sec, which I believe is the connection timeout. I've included a pic of a wireshark ble sniff. The highlighted line is the last packet send by the server to the client. That explains the connection timeout as the c...

I've been trying to get the ESP32 to work as a BLE server with little luck. I just posted what appears to be a bug in the bug reporting section of the forum. Nothing I've tried so far has worked to connect with any app on my Android and I've found what appears to be suspicious behavior. I'v found th...

Can't seem to get my BLE app (ex. ble_spp_server) to send response errors. An "attribute not found" error response should be sent in response to a Read by Type request on handles 1-5 for GATT Include Declaration (0x2803). There are 5 bytes that should be sent. 01 - Error Response 08 - Op code in err...
