WS-Registers in Cdpd Mode, Logic Sleep | Sierra Wireless DART 300

User’s Guide			AT Command Reference
Table 12-4: S-Registers in CDPD Mode (continued)

Register	Description	Range	Default Units

31	Logic Sleep	0 – 2	0

Specifies the sleep mode of the modems logic circuitry. This allows additional power conservation over the basic CDPD sleep mode available in +WS175 (CDPD Sleep Idle Time). See the Product Specification for power consumption figures.

Logic sleep is entered when the modem has no active tasks and CDPD sleep has already engaged. It awakes when there is incoming data from either the host or the network.

The logic will automatically awaken long enough to service the network requirements of CDPD sleep mode. This means there is no loss of data from the network side.

Value Meaning

0Disable logic sleep. (Default)

1Enable sleep. Awakes on incoming character.

2Enable deep-sleep. Awakes within 80ms after the start of the first incoming character from the host. Characters sent to the modem during this wake-up period are lost.

12.3.2.WS-Registers in CDPD Mode

Table 12-5: WS-Registers in CDPD Mode

Register	Description	Range	Default Units
45	PAD – Packet Service (DTE side stack)	0, 1, 3	3

Specifies the packet assembly / disassembly service to be used when the modem is on-line.

Value Meaning

0UDP

1TCP

3SLIP (Default)

4PPP

NOTE: You cannot change packet service modes if the modem is in the on-line condition. You must close the current session before changing modes. If there is an active session, attempts to change this register will fail with the ERROR result code returned.

50Normalized Signal Strength (Read Only)0 – 100

Returns a value indicating the normalized signal strength. Values range from imperceptible signal (0) up through adequate signal (~50) to full-scale signal (100).

This number can be converted to RSSI (dBm) using the formula:

[(+WS50) ⎟ 2 ] – 113 = RSSI
