Dear Quectel support team,
we are currently working with RG255C-GL module and we are starting the PTCRB certification process.
The latest firmware version we had previously received from Quectel is: RG255CGLABR01A04M4G_A0.300.A0.300
This version includes most of the features we need for the European market, such as VoNR, VoLTE and GNSS.
The latest modules we received from Quectel are loaded with version: RG255CGLABR01A05M4G_A0.300.A0.300
According to the Firmware release history included in the release notes, this is an evolution of the previous A04M4G version.
However, when starting the PTCRB certification process, we found that the latest PTCRB-certified firmware version is:
RG255CGLABR01A10M4G.
We obtained the following firmware package from our distributor:
RG255CGLABR01A10M4G_A0.001.A0.001
At this point we have some concerns and would appreciate Quectel’s clarification:
- Is RG255CGLABR01A10M4G an evolution of the A05M4G firmware version, or does it belong to a different branch?
- Could you please confirm whether the RG255CGLABR01A10M4G_A0.001.A0.001 firmware includes the features required for the European market, specially VoLTE, VoNR and GNSS?
- We understand the A.300 firmware versions may be related to the European RED DA certification. Would there be a RG255CGLABR01A10M4G_A0.300.A0.300 firmware version?
- Is it possible to use the same firmware version for both European and North American markets, or should different firmware branches be used depending on the target certification and region?
- What is the recommended way to stay updated with the latest official firmware releases and certification status, instead of discovering certified versions through the PTCRB website?
We would appreciate any official guidance regarding the firmware version evolution, applicable certification status, and recommended firmware version for a product targeting both European and North American markets.
Thanks and best regards.
