I want to configure a wireless LoRaWAN dongle via AT commands by using the echo command in the ubuntu terminal but the dongle doesn't seems to be responding with any feedback messages at all. After echoing the following command line, the terminal just go on to a new line without any messages / prompts.
echo 'AAT1 FwVersion' > /dev/ttyAMC0
(I performed a dmesg operation, the wireless dongle is in /dev/ttyACM0. No linux driver is provided for this wireless dongle but it can be configured via serial connection using AT commands.)
Am i sending AT command to the dongle the right way?
