Hi,
I'm trying to perform a DFU firmware update via command line using nrfutil dfu ble. The same update using nRF connect works fine. The dongle is flashed with connectivity_1.2.0_115k2_with_s132_3.0. Using the option verbose and some debug I can see that it's able to connect to the target (buttonless DFU) and transition the device into DFU, reconnect to the target (with address + 1) and start the procedure. It writes few characteristics:
handle, uuid, data
18 0x01 [2, 0, 0]
18 0x01 [6, 1]
18 0x01 [4]
18 0x01 [6, 2]
18 0x01 [4]
18 0x01 [1, 2, 0, 16, 0, 0]
but it stops in a write request with a "TypeError: 'NoneType' object has no attribute 'getitem'g" error. It seems that the function doesn't return with a result, maybe because it's interrupted by something(e.g. timeout).
I'm using Linux but even with windows and nrfutil.exe I stumble in the same identical error.
