Using the AT Command Tester tool,
- Set the SIM7000A preferred mode to NB-IoT.
- Get the supported SIM7000A bands for NB-IoT
- Get the current configured bands for NB-IoT in SIM7000 module.
- Set the desired bands for NB-IoT operation.
- Get the current system info.
You can also configure for NB-IOT operation using AT Command Scripts.
Try the below script 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 NB-IOT operation
//Get the preferred mode
//Set preferred mode to NB-IOT
//Get the supported bands for LTE CAT-M and NB-IOT
//Get the current bands for LTE CAT-M and NB-IOT
//Set NB-IOT bands
//Get the system mode
Output of the script file
Preferred mode is NB-IoT
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
