HL76_rpi

Project to automate IP connections on the Raspberry Pi with the Sierra Wireless HL76

Assumptions

The scripts are installed in folder ~/pilot/

The scripts are executed from ~

Tested on (ATi9)

Settings

File commandPort.cfg contains the path to the tty to use for commands. Edit commandPort.cfg to change the port used.

Base scripts to run to control the pilot (HL76) board

Restart the HL76

. ./pilot/pilotRestart.sh

Start IP on the HL76

. ./pilot/pilotIp.sh

Power on the HL76 (if connected to a RPi via the header)

. ./pilot/pilotOn.sh

Issues

Note that ttyACM0 has been used in this example. This is because with if ttyACM2 is used the AT+CGDATA="M-RAW_IP",3 fails or crashes the HL device. All FW versions tested

There is no error handling

FW 2.23 - the restart script seems to break something AT+COPS doesn't respond after the pilotIp.sh. It looks like there are responses in the stream (OK or ) which are upsetting the pilotIp.sh sequence.

Note the . or source is needed because variables are globally shared by some of the scripts
