Re: gatts_profile_event_handler returns ESP_GATT_CONGESTED and ESP_GATT_INTERNAL_ERROR

Just like you said, congest error means that peer device cant handle so many read/write/notify/indicate requests in short time. You can try to change connect parameter after connection: https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/bluetooth/esp_gap_ble.html#_CPPv430esp_ble_gap...

Re: ESP32 Bluetooth SPP with bidirectional communication (send and receive)

If you are flashing this code, i am guessing it is just echoing received data: case ESP_SPP_DATA_IND_EVT: #if (SPP_SHOW_MODE == SPP_SHOW_DATA) ESP_LOGI(SPP_TAG, "ESP_SPP_DATA_IND_EVT len=%d handle=%d", param->data_ind.len, param->data_ind.handle); if (param->data_ind.len < 1023) { snprintf(buf, (siz...

Re: Bluetooth air mouse using MPU6050 and ESP32

It all depends how your mouse should react on moves. For example you can use only gyro to set cursor absolute position, which requires to change mouse report map just a bit, or you can use relative positioning and combine gyro + accel to calculate relative value sent as cursor move.

Re: ESP32 bluetooth

Its because even if you turn on bluetooth on PC it wont start advertising by itself, you have to turn on advertising (its called visibility, or something like that).
