EG915Q-JP LTE module firmware update

IoT Modules LTE Standard Module

Hi. I want to do LTE module firmware update on EG915Q-JP. I find there are two ways to do LTE module update: DFOTA and Emergency download.
For DFOTA, our firmware version is Quectel EG915Q-JP Revision: EG915QJPLGR01A05M04. Could you provide delta firmware package(include .par file and .bin file) for us?
For emergency download, what Quectel tools do we need for firmware update and also what firmware do we need? Currently, I can’t figure out how to do it.
For above method, which one do you prefer to do firmware update? Could you give us some suggestions. BTW, we already have HTTPS server.

Email: nan.wang@murata.com.
Thanks.

Hi Wang Nan,

Currently for DFOTA EG915Q-JP Revision: EG915QJPLGR01A05M04, we only have Beta version of target firmware.

For emergency download mode, I will email you separately.

Hi, Redzuan:
Thanks. Could you send me the delta firmware package for DFOTA? It seems I don’t know what you mean about “we only have Beta version of target firmware”?

For emergency download mode, I see GNSS firmware upgrade. But what about LTE firmware upgrade? What tools do you use and also what firmware file do you use? Could you send them to us?

BRs.

Hi Wang Nan,

Sorry to make you confused. Beta firmware means it is only for our development purpose and not mass upgrade. May I know what project you are onto now?

For the standard firmware upgrade procedure, the method is the same as what I shared with you earlier via email. It essentially upgrades the EG915Q‑JP.

Sorry for late reply. Currently it is not convenient to disclose and I will wait for HQ response. There is no tools to do upgrade. What tools do you use? Thanks.

BRs.

Hi Wang Nan,

The tool used for offline firmware upgrades is QFlash.

Thanks. There is another question about GNSS function of EG915Q-JP. We want to get NMEA message from GNSS and see there are two modes: All-in-one Solution and Stand-alone Solution. But there are also USB and Main UART and GNSS UART. It seems confusing to us. When we use all-in-one solution, we only use USB port to get NMEA message. Is it right? When we use stand-alone solution, we must use GNSS UART to get NMEA message or we can get NMEA message from USB? BTW, is there any document about GNSS AT commands? Thanks.

Hi Wang Nan,

Sorry for very late response.

For your first question, yes, when using the All‑in‑One GNSS solution, you can rely solely on the USB interface to receive the NMEA messages. GNSS is enabled through AT commands, and the NMEA output is available directly on the USB NMEA port, which is why most users choose USB instead of adding extra UART connections.

For the second question, in Stand‑Alone GNSS mode, the NMEA stream should be taken from the GNSS UART. In this mode, the GNSS engine works independently, while the USB ports belong to the LTE baseband. Because of that separation, NMEA over USB isn’t supported or guaranteed when GNSS is running Stand‑Alone. Using the GNSS UART is therefore the recommended and reliable approach.
