We’re using the EC21-A modem and looking for the most recent version of Quectel firmware to debug some issues that we’re having with our hardware. The modules we’re using currently have firmware version EC21AFAR05A07M4G.

Can you share the latest version of firmware with us? Is the forums the only place to find this information?

Is there any firmware update?

Hello, we are working with several EC21-AUX modems, the fw version is EC21AUXGAR08A03M1G, ¿how can I keep these modules updated? ¿Where can I download the latest firmware version available?

For the lastest firmware version, the only way till now is asking in the forums, querry with the sales, with the local FAE.
I will send the lastest to you.

Thank you @Bean.Wang-Q

Hello @Bean.Wang-Q the firmware of the modules we use is EC21AUX… but the firmware we received is EC21EUX…

@gomezluisfe Sorry.
