Connect to LTE-M for quectel BG-96
I think this should be the sequence to connect to LTE-M for the BG-96
//First do a reboot
//Choose Operator and RAT type
//Choose communication band for LTE-M to 1800MhZ ->Band 3
(relates to 4 in below AT command)
//Configure Network Category to be Searched
//Set scanning network to LTE-M first than NB network
//Configure RAT(s) to be Searched (LTE-M - band 3 = 0x4)
// enable scrambling
//Switch the module to full functionality
//Show PDP Address
//Check if the device is attached to the network
If the response is 1 it means attached
//Setup a UDP socket (put your target here)
//Send some text data
//Type for example “Hello World”
//And a second time, since the first ever UDP message is used for registration. This message you should now receive in your own environment.
//You can also send data via UDP in HEX as follows
You have now successfully sent your first UDP message(s)!
@eric-barten Thanks for sharing these commands!
i do have 1 comment regarding the AT-commands.
doesn’t seem to work on firmware version: BG96MAR03A03M1G
so i think it should be: AT+QCFG=“nwscanmode”,3,1
and AT+QCFG=“gprsattach”,0 is no longer a supported command in this firmware version.
if all other commands are followed you can get a succesfull connection with LTE-M.
@eric-barten Thank you for sharing these commands
I would like to point out a minor change that would be required in the AT+COPS command for operator selection.
I think it should be:
AT+COPS=1,2,“20416”,8 instead of AT+COPS=1,2,“20416”,9
As ‘9’ is for CAT-NB1 and 8 is for CAT-M
