I’m having a project doing M95 module with MQTT feature
when I send two AT commands “AT+QMTOPEN=?\r\n” and “AT+QMTCFG=?\r\n”, it always responds “error”
I’ve already init it
send: AT+QMTOPEN?
receive: +CME ERROR: 100
send: AT+QMTCFG=?
receive: +CME ERROR: 100
send: AT
receive: OK
send: ATE0
receive: OK
Has anyone ever done and had the same problem?
Thanks for watching!
