EM9190 latest firmware?

Hello, what is latest available firmware for a revision G EM9190?
I have SWIX55C_00.16.04.00 000000 jenkins 2020/06/02 04:19:42 and have seen that some of the documented AT commands return ERROR. I wonder if there’s a more recent version available.

Thanks
Rick

Hi @pizzi

Currently, the EM9190 firmware has not been published on source.sierrawireless.com
https://source.sierrawireless.com/devices/em-series/em9190/#sthash.xYNHtYbM.dpbs

Please contact your reseller or distributor directly in this case.

I don’t have a distributor, I am an independent engineer and got just this one unit I’m testing now.
In addition to many commands not implemented and/or just returning ERROR, I seem to be unable to aggregate more than 1 band (i.e. it only does 2CA), where other modems I have (Quectel EM20, RM500Q) aggregate all the 4 available bands (B1, B3, B7, B20). I really hope this is a firmware issue and I don’t understand why you can’t publish the firmware for the EM9190 like you do for previous models.

Thanks

So, my unit has 00.16.04.00_Generi_010.003_000 and I have seen around people with what seems way more recent firmware for this modem, e.g. 01.04.01.01_Generi_013.001_000.

Can you please provide me the latest production release (generic)? I just inherited this module for testing and don’t have a reseller I can ask this to. Other vendors like Quectel have no problems helping people with an updated firmware. I am facing CA issues in LTE mode and am not able to evaluate the modem properly in this situation. Thank you.

Hi @pizzi

I don’t have EM9190 firmware. Please submit “Contact Us” on sierrawireless.com for support in this case.

That requires a support contract that I do not have.

@pizzi

The units to date have not been on general sale and you must have acquired it through one of our distributors as we have not been handing them out (as they are both expensive and a limited number), it is through this path you need to go.

This came to me from a colleague. I believe that he got this from Emax Group in China. I still do not understand why you can’t just provide the latest firmware for an unit that was regulary bought (this is not a sample). I can provide the IMEI for you to check.

Thanks
Rick

@pizzi

We do not post firmware that is not commercially available (and has hence gone through all of the relevant validation and certification testing, especially on something as new as the EM91) publicly. The unit that you got hold of, I suspect, were one of a few that escaped our control.

You need to go through the Emax group since this was your commercial route.

I understand that you do not post these until fully tested, but you could help by providing that on request with all the usual disclaimers. I work with Quectel also and they did it a number of times already. Anyways this is your decision/policy and I accept it, but sad that I can’t further test the module that I have here just because of that. Regards, Rick Pizzi
