oFono - Open Source Telephony ***************************** 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 220.127.116.11.96 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.
