Re: Huawei E1550 with pyserial hangs up raspberry pi

It seems this is software problem of raspbian.

Using pidora - works fine. The only difference I have to close serial port before opening like

Code: Select all

    ser = serial.Serial(serial_name, 115200, timeout=2)
    ser.close()
    ser.open()

Re: Huawei E1550 with pyserial hangs up raspberry pi

Well, don't think this is hardware error. I have another raspberry pi (china) and the behaviour is the same. You advice helped me, I got kernel panic message (see screenshot), no idea what to do :( Looks like raspberry still can't replace x86 miniitx pc... http://i57.tinypic.com/nv5v92.jpg http://i5...

Huawei E1550 with pyserial hangs up raspberry pi

Hello,

My raspberry pi has last raspbian distro and powered with 1A/5V. I use 4 USB modems Huawei E1550, connected via active USB hub. When I try to send AT commands in loop using python-serial - raspberry is freezes. Unfortunately, no logs to debug this issue.
Has anyone run into the same problem?
