8400 GPRS Cradle Reference Manual
1.1 WORKING MODES
1.1.1 TRANSPARENT MODE
In this mode, the cradle acts as a physical layer bridge, and therefore, the mobile
computer can work in any protocol behind TCP/UDP by using socket function calls. All it
requires is use AT commands to configure PIN code and GPRS AP name first, and then
follow the C or BASIC programming flow of WLAN Example (802.11b/g). For details,
please refer to a separate programming guide.
If CHAP is enabled, you must configure the settings from the mobile computer.
It fails to initialize a connection in the following conditions: (1) PIN code and GPRS AP
name are not configured correctly via AT commands, and (2) CHAP settings are not
configured correctly on 8400.
