Help_need :pc_ble_driver_py.exceptions.NordicSemiException: Failed to ble_gattc_write. Error code: NrfError.rpc_no_response

Hi @ThomasGerstenberg,

I hope this message finds you well

If I write chunk data (MTU size : 244 ) continuously using the write without response function (await char.write_without_response(file_data_to_encrypted).as_async() ), I occasionally get the error pc_ble_driver_py.exceptions.NordicSemiException: Failed to ble_gattc_write. Error code: NrfError.rpc_no_response. Why does this happen?"

Traceback (most recent call last):
File "/home/andrews/.local/lib/python3.10/site-packages/blatann/utils/queued_tasks_manager.py", line 36, in _add_task
task_complete = self._handle_task(task)

pc_ble_driver_py.exceptions.NordicSemiException: Failed to ble_gattc_write. Error code: NrfError.rpc_no_response

so do you have any ideas how to recover from this properly?

Thanks for your support
Andrews
