Test LTE CAT-M in SIM7000 in Script Mode
Using the script mode in AT Command Tester tool, send batch of AT commands to configure LTE CAT-M operation in the SIM7000 module.
Try the script included in the AT Command Tester tool.
//The AT commands in this script are applicable for SIM7000 modules only
//Check SIMCOM Module AT Command documentaiton
//Configure for LTE CAT-M operation
//Get the preferred mode
//Set preferred mode to LTE CAT-M
//Get the supported bands for LTE CAT-M and NB-IOT
//Get the current bands for LTE CAT-M and NB-IOT
//Set LTE CAT-M bands
//Get the system mode
Output of the script file
Preferred mode is CAT-M
Supported bands for CAT-M & NB-IoT are -2,3,4,12,13
Current CAT-M bands are -2,3,4,12,13
Current NB-IOT bands are -2,3,4,12,13
