GprsPlatformService (latest)

Figure 13 shows the default view for the GprsPlatformService in a JACE running AX-3.6 or build 3.5.31 or later (the Gprs Platform Service Plugin) view.

Figure 11. GprsPlatformService under PlatformServices in station running AX-3.6 (or a later AX-3.5 build)

This view is identical to the GPRS Modem Configuration view available in a platform connection. For related details on this view, please see the following sections:

Required platform GPRS setup, including Key GPRS modem properties.
Reference information on the GPRS Modem Configuration view.

In addition, many GprsPlatformService properties are available by selecting its property sheet view. See Properties of GprsPlatformService.

Properties of GprsPlatformService

Figure 12 shows the many properties of the GprsPlatformService.

Figure 12. Properties of GprsPlatformService in station running AX-3.6 (or a later AX-3.5 build)

As shown above, all properties default to read-only, and are grouped under two containers:

Settings

Child properties reflect the current configuration values, which can be modified using the default view (Gprs Platform Service Plugin) on the GprsPlatformService.
Runtime Data

A child container under Settings, where its child properties reflect various runtime data about the modem and its connection. Most of these properties are visible on the “GPRS Runtime Data” tab at the bottom of the Gprs Modem Platform Plugin view. Properties are as follows:
- Manager Status
  
  Text string of first line of file “/dev/gprs/manager” (always shows GPRSD).
- Data
  
  Results returned from reading “/dev/gprs/data”, concatenated into a single text string. Includes properties and values below starting with Rssi through Imei. If a read error occurs with this file, it will indicate a message similar to “resource manager UnresolvedException”.
- Status
  
  Either {ok} or {fault}. If “/dev/gprs/data” is available and readable, then {ok}. If gprsd is not running (or it has shut down/not started for some reason), then {fault}.
- RSSI
  
  Received signal strength indicator (i.e. number of “bars”), as a numeral from 0 to 5. Status follows Status property above.
- Roaming
  
  Whether or not the connected cell is in-network. Status follows Status property above.
- On Demand PPP
  
  Either true or false. Reflects the platform configuration as shown in the “Provider” section of the Gprs Modem Configuration view. See Provider.
- Ip
  
  IP address of this JACE via the Service Provider’s VPN network, providing PPP is active. If PPP is not active, this is an empty string (with status following Status property above).
- IMSI
  
  International Mobile Subscriber Identity. Unique identity for this cellular device, incorporating the SIM card identity.
- IMEI
  
  International Mobile Equipment Identity. Unique ID for the actual GPRS modem device, reflecting a code incorporating the modem manufacturer and model.
- SIM
  
  SIM, or Subscriber Identity Module. Unique ID of the SIM card installed in the GPRS modem.
