I’m using the Q24Plus in an embedded application. I am getting a +CME ERROR: 805 response to the AT+CCID command. Since I hadn’t planned for this response it upsets the state machine. The AT_Command_Interface_Guide_Open_AT_Firmware_v6.57d.pdf guide states that I should always at a minimum receive an “OK” response. Here is the problem trace:

Note that the additional text in the trace is just debugging information printed out during the initialization process.
