I would like to be able to use the Nordic Connect app for debugging and be able to observe the current UUIDs/handles of my attributes as I change them.
I have attempted to connect a perihperal and refresh the new UUIDs/handles in the Nordic app to no avail
settings > refresh services
I read in the specs that I should add the GATT service changed characteristic if my peripheral's service UUIDs or attribute handles are expected to change, like for example in the case of a DFU.
So in the ble_evt_handler
in the BLE_GAP_EVT_CONNECTED
I have added the following code from the multi-connect example
case BLE_GAP_EVT_CONNECTED:
// ....
err_code = sd_ble_gatts_service_changed(m_conn_handle, 0x0000, 0xffff);
if ((err_code == BLE_ERROR_INVALID_CONN_HANDLE) ||
(err_code == NRF_ERROR_INVALID_STATE) ||
(err_code == NRF_ERROR_BUSY))
{
// Those errors can be expected when sending trying to send Service Changed indication
// if the CCCD is not set to indicate. Thus set the returning error code to success.
SEGGER_RTT_printf(0,"Client did not have the Service Changed indication set to enabled. Error: %u\n",err_code);
err_code = NRF_SUCCESS;
} else {
// Print's Error: 6 (NRF_ERROR_NOT_SUPPORTED)
SEGGER_RTT_printf(0,"Error: %u\n",err_code);
}
// ....
The above code prints Error: 6 (NRF_ERROR_NOT_SUPPORTED)
Any advice? Thanks
