LTE strength

You can use a variety of AT commands in order to read / write to the modem. One command that we often use to query signal strength is
AT+QENG="servingcell". You can send this command and read the output to the terminal all in a single command usingecho -ne "AT+QENG=\"servingcell\"\r" | busybox microcom -t 1000 /dev/ttyUSB2. -
thank you I will try that
-
@tom said in LTE strength:
busybox microcom -t 1000 /dev/ttyUSB2.
Hi just one question what does this mean ? : busybox microcom -t 1000 /dev/ttyUSB2
-
@Aldo-Castro-Freire microcom is a program that can be used to talk to devices over a serial port (
/dev/ttyUSB2). It handles sending AT commands to the modem cleanly. -
I also have another modem that is 5g that I would like to connect to the microusb? what device would that be ? it would be ttyUSB1 ?
-
What 5g modem are you attempting to use? The drivers would need to be integrated into the kernel in order for it to be recognized.
-
I am getting "ERROR" when running this command
-
Check here for Sierra's AT command documentation: https://source.sierrawireless.com/resources/airprime/software/airprime_wpx5xx_wp76xx_wp77xx_at_command_reference/
-
I am not sure but none of the commands are running.
Also, it does not have the command AT+QENG for me to check out -
Can you show an example output of what you are seeing? Also, which modem are you using?
