What’s the adequated procedure one should take to properly start the BG95? I mean, I’ve bought an evaluation board for BG95 and it seems to work different than the chips that I’ve bought.
-
On the EVB:
** When I press the PWRKEY, the module powers up and spits on the UART messages like “SMS READY”;
** The module always fetches for the NITZ, syncing it properly when I connect to a PDP Context. -
On the SMD modules I’ve bought:
** Sometimes it starts on an unkown state: the AT+CSQ command returns 99,99 and I can’t connect to any MT, then I must restart the module a few times before it starts again on the work properly.
** These modules only outputs a “APP RDY”, never the “SMS READY” thing, like my EVB version.
** Sometimes they sync with NITZ, sometimes they don’t.
So, I need to reliably start up the SMD modules I’ve bought, and also be able to sync the RTC with NITZ. I’ve already executed the commands:
AT+CTZU=3
AT+QCFG="timeupdate",1
But it doesn’t seem to change a thing.
Another thing I should mention is that with my SMD modules they always automatically tries to connect to the last PDP Context it was connected before. Meaning I don’t need to execute AT+CGACT=1,1 to bring the pdp context up.
I feel like there’s some sort of commands I should send to configure it 
The output of ATI on the modules is:
Quectel
BG95-M3
Revision: BG95M3LAR02A03
OK
Anybody knows what I could possibly be doing wrong with both issues? The module sometimes starting on an unknown state and not synchronizing with NITZ.
