How to Change the Baud Rate of MOBITEK Q25 4G Modem

  1. By default, the baud rate for MOBITEK Q25 is “115200”.
  2. To change the baud rate of MOBITEK Q25 to another value and save it as default, MOBITEK Q25 needs to be connected to the PC using serial cable.
  3. Open Hyper Terminal, connect MOBITEK Q25 using “COM1” and set the baud rate to “115200”.
  4. Type “AT” in Hyper Terminal. If the response is “OK” then MOBITEK Q25 is successfully connected. If nothing can be entered in Hyper Terminal , then unplug and replug the serial cable to the serial port of the PC until “OK” is shown.
  5. In this example, the baud rate will be changed to “9600”. To do this, type “AT+IPR=9600;&W” in Hyper Terminal.

  6. At this point, nothing can be typed in Hyper Terminal because the baud rate setting has been changed from “115200” to “9600”.
  7. Disconnect MOBITEK Q25 from Hyper Terminal.
  8. Go to “File” -> “Properties”. In “Properties”, click on “Configure”. In “Port Settings”, change the baud rate to “9600”.
  9. Connect the MOBITEK Q25 to Hyper Terminal again. Enter “AT” and query the baud rate command. The baud rate should be changed to “9600”.

How to Upgrade or Downgrade the Firmware of MOBITEK Q25 4G Modem

Steps

  1. Run “QFlash v5.1”.
  2. Select the COM port number of “Quectel USB DM Port” (must use the USB port because serial port does not have “Quectel USB DM Port”).

  3. Set Baud Rate to 460800.
  4. Load Firmware Files.

  5. Upgrade firmware.

  6. Unplug the USB cable and plug it back. Use “AT+CMGR” or “ATI” to check the firmware version.

How to Send MMS Using MOBITEK Q25 Modem

Note:-

  1. The correct AT commands for sending MMS is saved in “X:\Reports by Trainees\Taufiq\A20-T-30-4G Modem (Q25)\MMS\MMS Script.ini”.
  2. The MMS settings (AT+QMMSCFG=”mmsc”, AT+QMMSCFG=”proxy, etc.) cannot be saved using “AT&W”, the settings must be re-set after modem is rebooted.
  3. Must use QCOM instead of Hyper Terminal to upload image file.
  4. When MMS is successfully send, the response is “+QMMSEND: 0,200”

 

AT COMMANDS FOR MMS

Note: This script is located in “X:\Reports by Trainees\Taufiq\A20-T-30-4G Modem (Q25)\MMS\MMS Script.ini”. It must be executed one-by-one because the delay time is not set. Load the script in QCOM to use it. The MMS Settings used is MAXIS’s MMS Settings:
