Thanks for you answer. Have you seen this project LinkIt_Assist_2502 ? (sorry cannot place URL, forum’s engine blocks it) I’m using it to start developing on Linux. Particulary, I found interesting Python scripts, like mon.py for captuirng data from debug serial port and uploader.py to send vxp to board’s internal memory (and to reset it). The uploader works well for me, it uses AT-coomand and opens port /dev/ttyACM0, so I suppose this is what you called “AT Command port”. mon.py opens /dev/ttyACM1 and tryes to catch messages sent by vm_log_debug() and etc calls (often misses them and this is my main concern). But your manual states:
/dev/ttyACM0 the application usb serial port interface
/dev/ttyACM1 MT2502 modem interface (AT Commands)
Probably just port enumeration issue, so I moved forward, built and uploaded Https-demo, trying to catch something on /dev/ttyACM0 using “screen /dev/ttyACM0” but nothing, then opened /dev/ttyACM1 and got parmanently changing garbage.
Am I doing something wrong?
