AVAILABLE FOR

A731 A733A732 A733GSM

DESCRIPTION Returns various status information.

ARAMETER None.

RETURNS A list of a device’s internal variables:

ID INFO rf_in rf_out date time ver clk stack cop batt temp

days_uptime hr:min_uptime rssi pmp_low pmp_high type slot

samples po err_level

The formats for the above parameters are as follows:

• rf_in and rf_out as a decimal (irrelevant for the A733GSM/GPRS)

• date as dd/mm/yyyy

• time as hh:mm:ss

• ver as x.x

• clk, stack, and cop as decimal; they represent internal housekeeping

parameters: the A733 uses cop to number watchdog occurrences, but

clk and stack are currently undefined

• batt as battery level using the standard voltage conversion equation (0 is

0 volts, 255 is 20 volts)

• temp as internal temperature in the A733 housing, which is device

dependent. The precision of the sensing element is low (±2°C), but it is

sufficient for battery power management (charge/discharge). To compute

the actual value (in °C), the following equation must be used:

Temp =

internalTemp * 400

255

- 68

• days_uptime in days; together with hr:min_uptime, it represents the

amount of time the device is up without a reset or watchdog

• hr:min_uptime in hours:minutes format

• rssi as decimal; it is the programmed value with the RSSI command

(irrelevant for the A733GSM/GPRS)

• pmp_low and pmp_high are the programmed values with the PMP

command (irrelevant for the A733GSM/GPRS)

• type is used to represent the device type; following types are assigned

currently:

0 for A730MD

1 for A720

2 for A730SD

3 for A720B

4 for A733
