@alzhao Following your recommendation, I opened a ticket with Quectel. Here is the latest response:
1.I see that the execution of other commands also has the problem of returning only OK. Can you provide the at log that the command can be executed normally until only OK is returned? I want to know what operations were performed in the process, thank you!
2.Do you currently use EVB for testing, can you follow the following methods to help grab Qwinlog, which will help us locate the problem?please execute at+Qcfg=" DBGCTL ",0 to turn on LOG switch
Can I do any of this directly on the XE300 ??
