| 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. |
