Objective

Quartz routers series use a combination of router and cellular module firmware to function. Router firmware can be updated by following the application note How to upgrade a Siretta Router Firmware Application Note

So far, updating router module firmware has been a complex one that involves opening of router casing, removing PCB assembly, detaching the cellular module, plugging the module into a USB adapter then update firmware using a tool called QFLASH. A lengthy procedure requiring Siretta Technical support.

This application note allows users to update the cellular module inside Siretta Quartz series routers using efficient and non-invasive procedure without disassembling the unit.

Solution DFOTA - Stands for Delta Firmware Update Over-The-Air. DFOTA allows users to update router module firmware using cellular network. Router is set to AT over IP mode where AT command AT QFOTADL is issued to initiate the update process and point to a location where delta firmware is stored.

Delta firmware file can be either stored in a remote HTTPS/HTTP server or FTP server, this application note covers the procedure were delta firmware file stored in HTTPS server.

Requirements Siretta Quartz Series Router (for this applicationQUARTZ-ONYX-GW42-5G (GL) was used)

Windows 11 Laptop with Tera Term Version 4.96 or above (Tera Term can be downloaded from the following link - Tera Term Link ).

URL where Delta Firmware file is stored.

AT Command over Internet Protocol Router Guide

Demonstration of Solution 1. Follow router quick start guide for initial router settings.

2. Wait for the router to connect to the cellular network.

3. Confirm that router has received IP addresses (See below).

4. Navigate to a Basic Network in router GUI.

5. Select Cellular tab.

6. Uncheck Modem Enable checkbox

17. Select Cellular tab.

18. Confirm Modem Enable checkbox is unchecked (See below).

19. Open AT Command over Internet Protocol Router Guide

20. Follow steps 1 to33 of the AT Command over Internet Protocol Router Guide.

Note: Router IP address in AT Command over Internet Protocol Router Guide is 172.168.1.1 which is different from the router IP address used in this guide (192.168.1.1). Replace 172.168.1.1 with 192.168.1.1 and continue with the rest of the application note.

21. You will be presented with Tera Term window.

22. You have now established connection with the cellular module inside the router.

23. Issue the following set of AT commands to query modem and initiate DFOTA process.

24. Issue AT CREG? - to Check the network registration.

192.168.1.1 - Tera Term VT

File Edit Setup Control Window Help

AT CREG?

CREG: 0,5

25. Receive following when registered to a local network: CREG: 0,1.

26. Receive following when registered to a roaming network: CREG: 0,5.

27. Issue AT CGPADDR=1 to Check if the context is activated.

192.168.1.1 - Tera Term VT

File Edit Setup Control Window Help

AT CGPADDR=1

CGPADDR: 1, 10.188.232.13

OK

28. Receive IP address when context is activated: CGPADDR: 1, 10.188.232.13

Note: If no IP address is returned issue AT CGACT=1,1 to activate context or contact [email protected]. Your returned IP address may be different from the above depending on your SIM card provider.

29. Issue AT QGMR to receive full current firmware version.
