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?”
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.
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.
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.
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).
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 …
