Dear Sir,
+CFUN:5 means that the module enter into FTM(RF test mode) ,you can use the following AT command to let module exit the FTM:
AT+ QRFTESTMODE =0 // exit FTM
If the above AT command can not take effect, you also can use the following method, please follow up the following steps to set it with QXDM tool. Hopefully it is useful to you. Thanks!
