Recently we get the new requirement from Huawei & STC for NB-IoT GPS Tracker , the clients would like to config the network and bands by USB Cable. After discussing our engineers ready for it with a new NB-IoT GPS device.

In the process we found the bug in BG96B module:

  1. You may be misunderstood according to the band configuration parameter format :
  •  There are a “Band Configuration” commands in the manual of “BG96_AT_Commands_Manual_V2.0”

NB-Iot-band-config

  • Follow the commands but it will show “ERROR” as follow:

  • How to fix it?

1>Have to remove the “0x” when you configure the bands or it will show “ERROR”;

2>The correct configuration format is :  AT + QCFG = “band”, f, 4,10,1

  1. The bug after configuring the bands
  • Following is the log after debugging BG96 UART port and you can see after configuring the band and restart the module, the BG96 have no response for AT+CPIN? commands

  • Mictrack’s engineers tried to test it in USB mode but still fail, finally, we found all of the AT commands also have no response after reboot the module.
  • The engineer collect the bug and submit to the Agent of Quectel, however, have not got the better support and it’s very depressing and regrettable
  • How to fix it?

1>We have verity the BUG and try to feedback to the FAE, finally get the new firmware but without any explanation.

2>After upgrading it and the bug will fix in the new firmware. The FAE does not know it at all and a bad attitude.

3>The new firmware version BG96MAR02A05M1G.

4>upgrade the tool QFlash_V4.3

5>PC driver Quectel_BG96_Windows_USB_Driver_V1.0

6>he upgrade process
