Purpose
|
|
=======
|
|
The purpose of this document is to identify issues and configuration
|
|
requirements with Telit's modems.
|
|
|
|
HE910
|
|
=====
|
|
|
|
GPS:
|
|
To enable location reporting on the Telit HE910 the modem needs to be
|
|
switched to Port Configuration #8. Please refer to Telit's
|
|
'HE910 UE910 Family Ports Arrangements' section 4.1.3 for rationale and
|
|
'AT Commands Reference Guide' section 3.5.7.1.96 for specific AT command.
|
|
After setting the configuration, a power cycle is required.
|
|
Port Configiuration #8 is available since firmware 12.00.004. Firmware version
|
|
can be checked using 'AT+CGMR'.
|
|
|
|
LE910 V2
|
|
========
|
|
|
|
Default USB composition of LE910V2 uses PID 0x36 (AT#PORTCFG=0)
|
|
and consists of 6 serial ports (CDC-ACM standard, /dev/ttyACMx)
|
|
and 1 network adapter using CDC-NCM standard (wwanx or usbx).
|
|
|
|
NCM interface configuration follows Telit documentation
|
|
(both documents available on Telit Download Zone - registration required)
|
|
"GE/HE/UE910, UL865, LE910 V2 Linux USB Driver - User Guide r0"
|
|
(document 1VV0301255 Rev.0 - 2016-01-22)
|
|
and "Telit LE910-V2 NCM SETUP r3"
|
|
(document 1VV0301246 Rev.3 - 2016-11-29).
|
|
|
|
After context is setup, NCM mode activated and PDP context activated
|
|
connection configuration can be read using
|
|
AT+CGPADDR=context_id and AT+CGCONTRDP=context_id commands.
|
|
This is done automatically and results available via
|
|
org.ofono.ConnectionContext.GetProperties DBus method.
|
|
|
|
Then Linux network interface needs to be configured:
|
|
ifconfig <Interface> <Address> netmask <Netmask> up
|
|
route add default gw <Gateway>
|
|
arp -s <Gateway> 11:22:33:44:55:66
|
|
|
|
Only after these steps network interface is usable.
