Hi AB! I bought an 502 from you, but I can not earn any data from it.

BEFORE PLUGED INTO USB PORT:
$ dmesg | grep tty
[ 0.000000] console [tty0] enabled

AFTER PLUGED INTO USB PORT:
$ dmesg | grep tty
[ 0.000000] console [tty0] enabled

$ [Errno 13] Permission denied: ‘/dev/ttyACM0’

$ sudo chmod 777 /dev/ttyACM§

$ echo “AT+SCAN?” > /dev/ttyACM0

NOTHING HAPPENS… :frowning:

$ miniterm.py /dev/ttyACM0 115200
— Miniterm on /dev/ttyACM0 115200,8,N,1 —

NOTHING HAPPENS… :frowning:

Do some have an idea how can I use the device??
Thank you!

Please append “\r\n” to the line end of the AT command.

Please write down the command precisely! I’ve tried that everyform but the same resull: nothing. Thank you!

The default baud rate is 9600 not 115200. I’m not master for linux. So I do some testing on my macOS.

  • Open a terminal and type miniterm.py /dev/tty.usbmodem93 9600. (it’s show as usbmodem93 on my laptop)
  • Open another terminal and type command echo AT > /dev/tty.usbmodem93. I got “OK” at miniterm screen.

Let me know if this work for you

Update:

The default baud rate is 115200 not 9600.
