I try to connect my HL7800-M to a network using a mangOH red. The module does not connect automatically when following the getting started guide for HL7800 AT+KTCPCNX=1 did not succeed.
So I wanted to list the available networks using AT+COPS=? and do the connecting manually.
I am using the SierraWireless SIM delivered with the mangOH (already registered on eu.airvantage.net as discribed in the getting started guide) and the AT+COPS=? gives an error.
AT+COPS? +COPS: 0 OK AT+COPS=? (+CME ERROR: 515)
The response to AT+COPS=? (shown in brackets) overwrites the command on the same line (no LF/CR). What is strange is that I don’t find any reference to the error code in the AirPrime - HL78xx - AT Commands Interface Guide.
Any suggestions what this error means?
As a reference I also have the WP7702 on a mangOH red. Here I can scan for networks
