Details:
Hello again. Hoping someone can help.

When running “sudo pppd call gprs” the output is:

Connect script failed

I think this is due to my APN having a space in it (“Spark NZ”). When i try without a space (“SparkNZ”) the connect script runs but obviously does not connect.

Minicom:
output from “at+cops=?”

+COPS: (1,"Spark NZ","Spark NZ","53005",7)

Output from “at+csq”

+CSQ: 30,99

output from “at+cops=1,0,Spark NZ,7”

+CME ERROR: 30

Thank you for reading and any info would be great.
Cheers,

I have just tried this with a different sim card and APN with no space (“2degrees”) and it worked fine.
Also, to be clear i am required to use the “Spark NZ” sim.
Thank you!

Hello @shirtna

you could try to use the numeric value instead. E.g. something like:

at+cops=1,2,53005,7

Thanks

Hello @felix

Thank you for your reply.

How would i apply that to the pppd connect script?
Would it just be

sudo /usr/local/rak/lte/ppp-creator.sh '53005' ttyAMA0 921600

Thanks again

Hello @shirtna

no, I don’t think so. I understand the script expects the APN as parameter which is different from the operator name or number.

Check with your provider about the correct APN. Maybe see here.

Thanks
Felix

Hello again @felix.
Thank you for your response and apologies for not replying, I’ve been away.

I have tried all the APNs in that link and none of them seem to work. The only way I can get the rak2013 to connect is by putting in a sim card from 2degrees and setting the APN to “2degrees”. 2degrees APN (internet etc) settings don’t seem to work either.

Cheers.

Hey Felix,

This didn’t work either (in Minicom)

at+cops=1,2,53005,7
