Q2686 - USB - Flow control



Changing an USB flow to Data mode, should that be a problem?
My device is Q2686, OpenAT v4.01, Firmware 6.60

My test-application subscribes to both UART 1 and USB flow. At first both channels are in AT mode and working fine. UART 1 can be switched to DATA mode while USB still in AT mode. Switching USB to DATA mode does not have the same effect, as it stays in AT mode. I monitor the return value after “adl_fcmSwitchV24State(…)” and it returns OK, but USB is not in DATA mode!

I’m testing my applications in target mode.

Does anyone know, or tried it before?



How did it go with the change to data mode? Do you have it working now? I’m interested in the same. I haven’t tried it yet, but if there are any tips…



Hi Dave

USB in data mode is working fine now. I had some problems in the beginning, but it is up and running now. I’m not sure what caused the problem, but currently I’m subscribing to an at command which handler changes the state of the usb flow.
