EM7565 Firmware Problems with CA?

Its the same for me. B3 + B1 does a strange behaviour.

RSRP-Main of SSC1 is anywhere below others where it can’t be in real.
All RSSI are so far apart that this also can’t correspond to reality. (In Addition RSSI of Main-Band is Jumping all over the chart)

The following charts are created with the output of the command “AT!GSTATUS?”

Hello, We cant get our EM7565 firmware to work with the test sim we obtained.

What firmware are you using? The generic one that came loaded does not seem to work.

What test sim or network sim are you using?

Thanks,

Bill

We are using the pre-installed pre-certified Generic version.

Model: EM7565
Revision: SWI9X50C_01.00.02.00 6ff48a jenkins 2017/09/29 05:54:26

We are all on Drei Österreich / Three Austria or simply “3”.

Please consider opening a new thread.

Hello Support Team,

same Situation here. Does anybody know when there will be a firmware update and when the module is integrated into FOTA?

Thank you,

Michael

Same with me. Only getting 41+41. I should be getting 41+41+41. Please let us know something. I spent a lot of money on a cat 12 that only does cat 6.

Any update on this?

Guys,

Just to answer the firmware availability question, the current build is release 7 (1.2.1), release 8 is scheduled to be out next week sometime which is intended to be the candidate release to start operator approvals with. As normal you need to go through your commercial channel to get your hands on newer firmware releases.

So no release on source.sierrawireless? Why not?

Because it is not declared as commercially available and hence we do not have a fully approved release yet for the M2M versions.

CA is still broken @ B1+B3 and 256 QAM doesn’t seem to work either (Operator: Hutchison Drei Austria / MCCMNC: 23210).

I can confirm @unknown’s findings using the new firmware.

For the EM7455, B1 + B3 was not a supported combination, only (B1 + B8), (B3 + B7) or (B3 + B2) (and some more outside Europe), as noted in the PTS.

For the 7565, the PTS lists no band combinations yet, so (B1 + B3) support TBD, especially regarding supported BW and modulation.

R6 lists the supported band combinations (Feb. 18). And as I already noted in a previous post, all four streams work from time to time (very rarely), but not consistently.

PCC RxM RSSI:  -54              PCC RxM RSRP:  -74
PCC RxD RSSI:  -57              PCC RxD RSRP:  -77
SCC1 RxM RSSI: -46              SCC1 RxM RSRP: -72
SCC1 RxD RSSI: -49              SCC1 RxD RSRP: -75
Tx Power:      -14              TAC:         .. (..)
RSRQ (dB):     -8.7             Cell ID:     ... (...)
SINR (dB):     21.0

All four streams are working at the moment. But letting the connection into idle will cause breakage again. Will we ever see a fix for this + 256 QAM? I see B1+B3 as supported in the document. My mobile UE works flawlessly with the same network and 256 QAM works as well.

All,

FYI there is a a new PTS which is about to be posted to the source which has a great big table listing of all of the CA combo’s.

Regards

Matt

That doesn’t solve the problem though. We already know that B1+B3 is supported.

Still struggeling with this issue. Is there any roadmap for a firmware with fixing B1+B3?

The chip set does what it does, the CA bands are set at product definition and do not change, we enable as much as we can given chip set capabilities and hardware restrictions (you can only fit so many bands on a single device with discrete radio components). So the short answer to your question is that if your CA requirements are not met in the current table then it is highly unlikely that we will ad it at a later date unless it is in a new product (which is not on the horizon or publicly announced).

Regards

Matt

The CA requirements are met! (B1+B3)

Is this a joke? I already mentioned two times that all four streams work from time to time. Why is that not going to be fixed? And where is the announced 256 QAM support?

I have spent € 220 on this module and now neither B1+B3 nor 256 QAM work … Next time I will think twice before buying a module from Sierra Wireless again. Releasing a firmware version from Nov. 17 in March 18 is a joke as well.

The main reason why I bought this module is B1+B3 and 256 QAM …
