Dear Crypto Fan,
Thanks for your inquiry in Quectel forum.
If you want to lock band 7, you can use the following AT command. Thanks!
1.Please use AT command AT+QCFG=“BAND” to check the default band setting;
2.Then use AT+QCFG=“BAND”,00,40,00; // lock to LTE BAND7
3.After finished the test, it is better to reset the band to the default value. Thanks!
Dear Cryto Fan,
You need to use AT+QCFG=“BAND” to reset it to the default value. So you need to check the default value before you lock it to BAND 7, then after test, use the above command to reset again. Thanks!
