@afzal_m Sounds good, how about BG600? - it has a similar FW to BG95/96

@afzal_m trust me Ive been pushing for it since I discovered that simcom had it last year but our choice of supplier for modules goes to Quectel so far.

@afzal_m its pretty amazing i have to say, you have no idea how many sims i have soldered in the last 6 years
now just hope you spread it onto the whole line of modules

AT+NSOCR=DGRAM,17,7000,1
AT+NSOST=0,172.27.131.100,15683,11,48656c6c6f20576f726c64

@afzal_m for those who are struggling with the last part

These two commands

AT+NSOCR="DGRAM",17,7000,1
AT+NSOST=0,"172.27.131.100",15683,11,"48656c6c6f20576f726c64"

Should be used without double quotes:

AT+NSOCR=DGRAM,17,7000,1
AT+NSOST=0,172.27.131.100,15683,11,"48656c6c6f20576f726c64"

and voila it works like magic

@afzal_m nevermind, unlike on all other Quectel EVBs the baudrate is 9600 for this KIT.

@afzal_m thanks for the nuSIM devKit!
Unfortunately having a trouble to connect to it. PC recognises 4 serial ports Channels A-D. But none of them react on AT commands. I used BC95-G-TE-B-KIT manual to connect, but no luck. Is there something specific about this board?

Cheers!

Good morning @afzal_m, is it possible this Sim requires 3v? This would explain weird behavior when the module provides only 1.8v

@afzal_m actually made a mistake about the module type, its BG600L, not BG96.
Now I switched to BG96 and was able to send a packet finally (thats the good news). Bad news is that module goes into power off mode after 30-60 seconds and Im not able to stop this. Would you have any advice?

Hi @afzal_m , thanks. I also contacted Quectel guys for help. But I tried 3 other different sims and AT+COPS succeed with them on Quectel EVB. Wonder if this could be connected with the fact that only NB-IOT is enabled for this SIM?

@afzal_m Im wondering if the SIM gets locked up on the first device it was inserted into?
I have nrf9160 kit and Quectel evb. First I inserted it into nrf9160 and I could complete AT+COPS command successfully. The problem is that this modem doesnt support AT commands to connect with UDP via NB-IOT, so I switched to my Quectel board on which AT+COPS didnt want to work properly.

@afzal_m I actually tried it with 9, it limits network connectivity to Nb-iot only, but no success still.

@afzal_m done

@afzal_m said in BG96 sim error:

Can you please try what happens after removing and replacing the simcard in the card-holder?

have tried removing inserting a few times, but didnt help. inserted my own sim and it worked, so there is some problem with the sim somehow?

Have just rebooted EVB, now IMSI reading is ok, but still cant set the operator

Hello,
Somehow I get a sim error when I try to get IMSI or set current operator:

/* Use AT+QCCID to query ICCID number of SIM card */

but it does read ICCID properly. Any idea what that could mean?

@afzal_m very exciting topic:) I haven’t got nusim devkit, but I’m very interested in the topic. Would it work on some specific modules, if yes on which ones? And when would we expect availability?
Thanks!
