Hi Members, i am using Quectel CC200A-LB module for satellite communication. when i was giving commands some commands are working like ATI, AT+QGMR, AT+GSN, ATV, ATS3, ATS4 etc…but some commands are not working like AT+QSCN, AT+QREG, AT+QSMGL, AT+QSMGS, AT+QSMGT, AT+QSMGC, AT+QRMGS. i am giving 5V supply to the module and also i checked outside like clear sky. what is the mostly problem.
Is there any URC after executing above commands?
I am getting these serial message responses from the CC200A-LB.
