NB-IoT  Module  Series 
                                                                                   BC660K-GL  Log  Capture  Guide

Run the command below on the AT port to set the baud rate of the logging port: 
AT+QCFG="logbaudrate",6000000      //Set the baud rate to 6 M. 
OK 
 
⚫   
1.  It is strongly recommended to set the baud rate to 3 M or higher. Otherwise, a lot of log messages 
may be lost, resulting in failures in later problem analyses. 
2.  For the details about AT+QCFG, see document [3] 
 
4.4. Database File Selection and Updating   
 
Different  firmware  versions  require  different  database  files  to  decode  the  firmware  correctly,  so  it  is 
necessary to select the correct database file before capturing logs. 
 
Click the icon in the upper left corner of EPAT to open the database window, as follows:
