EM7565: Aggregating B1+B3 does not work as expected

IoT Modules MC/EM Series

Yes it is a joke …

I was gifted an EM7455 and thought “cool, it supports simultaneous use of GPS, Glonass, Galileo and Beidou” and would have been perfect for my project. But of course, GNNS is totally broken as well. Positioning tracking works fine to a certain degree but the output of used satellites on the NMEA interfaces is FREAKING broken. Documented AT commands aren’t implemented or printing wrong data.

Now as a last ressort there would be the SDK. But its amazing documentation is full of mistakes and copy and paste errors … Not to mention it requires the unstable GobiNet driver … Unplugging the modem = Kernel panic or “stuck” driver.

Sierra + Quality Assurance = Biggest joke ever.

It’s been a month since my last message. I’m going to try following up on this thread monthly in the hope that someone from Sierra Wireless will change their mind about making us wait until June 2019 for this problem to be solved.

Is there any update for this month?

waiting over a year for a proper firmware :-1:

Don’t get your hopes up - nothing is released yet.

For the EM7455 the possibility to place and receive phone calls was announced in a “future firmware upgrade” but that never came. Which is sad.

Optional support for VoLTE and CSFB voice through future FW update

@Oedenburger
do you have an update when to release a new FW?

27

Pure waste of time to ask that question.

I raised the issue internally. That’s all I can say.

Awesome. Now I have two dead streams…

PCC RxM RSSI: -52 PCC RxM RSRP: -74
PCC RxD RSSI: 0 PCC RxD RSRP: -44
SCC1 RxM RSSI: -100 SCC1 RxM RSRP: -120
SCC1 RxD RSSI: -58 SCC1 RxD RSRP: -76
Tx Power: -3 TAC: … (…)
RSRQ (dB): -7.5 Cell ID: … (…)
SINR (dB): 0.0

The only reason why I haven’t migrated to another vendor by now is because I don’t really need that amount of bandwidth. The way you are dealing with your customers is still a joke though.

it’s kinda sad - just purchased 58 devices with sierra modems again cause we had no choice.

at home my module is just dust catcher and i’m using a nighthawk…

In a few weeks it’s June. Any news?

Nope. Ignoring still works best.

There is a stupid hack to get all streams working temporarily:

AT!SELRAT=01 # UMTS only
AT!RESET # Mandatory. It won't work otherwise.

And wait until the modem switches to LTE (or make a speedtest) and keep the connection alive. That’s actually another bug but who cares …

June is comming …
… is there any date we can expect the firmware-update?

34

We should start a bet wether they will release a firmware update in June or not. No wait, that would be too easy to guess.

Hello Folks,
Please understand that this Forum is perhaps not the right medium to discuss maintenance release schedules as release schedules & priority for those are driven by business cases as carrier re-certification of Firmware releases are required for subsequent maintenance releases and that is driven by the market demands + criticality of deficiencies that may need to get addressed. Firmware releases can only be made available once it is “certified”. I suggest you contact your seller/support channel for a detailed carrier release schedule & plans for this product. If there are any further specific technical issues we can help with on this forum, please feel free to reach out.
