Trying to set up Raspberry Pi with FONA module and 2G sim card from Hologram.
Currently able to do these things -
- power on FONA, receive LEDs as expected
- create serial connection, send AT and receive OK
- use this PPPD configuration
connect "/usr/sbin/chat -v -f /etc/chatscripts/gprs -T hologram" /dev/serial0 115200 noipdefault usepeerdns defaultroute persist noauth nocrtscts local debug
- turn on FONA ‘sudo pon fona’
After doing all of that I do not see a ppp0 interface in ifconfig.
‘cat /var/log/syslog | grep pppd’ includes these messages:
Connect: <--> /dev/serial0 ... PAP authentication succeeded Protocl-Reject for 'Compression Control Protocol' (0x80fd) received LCP terminated by peer Connection terminated. Modem hangup
I found a StackExchange post that references this issue where the solution was described as a ‘provisioning issue with my MVNO’.
Does the hologram configuration of sim card have anything to do with MVNO in my case or any other suggestions on how to proceed??
