Error receiving blecharacteristic value > 20 bytes written by connected client
Posted: Wed Dec 20, 2017 4:55 pm
Using Eclipse and ESPIDF most recent code.
ESP32 is set up as client and ble communications work fine in general. When the client (nRF Connect for testing) writes a text value to a characteristic, the callback onWrite event is triggered appropriately. If the value is > 20 bytes, all bytes are successfully read with characteristic.getVal() but I get the following error logged:
E (135716) BT: GATTS_SendRsp conn_id: 3 waiting for op_code = 00
E (135718) BT: Sending response failed
