Re: Quectel EM160 AT commands

I believe what it does with CA depends on the supported combinations for the bands you have available. Here we have B1 B3 B7 and B20 and no it will not do anything other than 2CA unless you restrict the band set. But I think that's just a not so mature firmware.

Re: Quectel EM160 AT commands

I am happy to tell you that, although not documented, the EM160 supports EM20 way of locking PCC to a cell id (and therefore a tower) using at+qnwlock=\"common/4g\",1,EARFCN,CELLID

Re: Quectel EM160 AT commands

I found a way to make it behave properly . Need to lock the explicit bands with AT+QNWPREFCFG="lte_band",1:3:7 then it will do 3CA or 4CA. If you leave it "free" it will stick to 2CA... buggy firmware, as usual from Quectel

Re: Quectel EM160 AT commands

I wonder if the EM160 performs any better than the EM20.
I just received my EM160 yesterday so I'll replace the EM20 I have been using since couple months and run some tests.

Re: Sierra EM9190 stuck in PCIE mode

correct but this is what quectel decideed it seems, EM20 will not receive firmware updates anymore and you can only buy it second hand now. I have one and is a decent modem, I am now waiting for the EM160 to arrive and compare the two.
