Cannot Establish Data Connection with Quectel EC25-A

jhwblender · July 1, 2021, 6:13am

I too am having this issue @saeed: I have a Quectel EC25-A (North America). When I run the command AT+QGMR I get EC25EFAR06A11M4G_01.001.01.001. As this was the same issue as desi76, I tried to download the correct firmware to flash, but the link is expired. Is there a permanent link for myself and others like me who are having the same issue?

Hey Please use this Link,

Since the FW keeps on updating after a particular period, We are not sharing a permanent link.

I have the same issue my EC25-A seems to be loaded with the wrong Firmware, can i get a copy of the correct latest Firmware for EC25-A?

Thanks

@mintaka
According to the output, the module seems to the EC25E, not EC25A.

Make sure the module is EC25A. Please download the right Firmware EC25AFAR05A07M4G_30.002.30.002 for EC25A.

Hi saeed, Do you still have this file? I’m running into the same problem but it looks like the link to the latest firmware has expired.

Please Download it from LINK
Note: It contains firmware for both EC25A and EC25E variants.

Thanks Saeed, the firmware upgrade was successful. I am able to connect to to Bell with no problem on EC25-AF variant modems.
