FDEV
DESCRIPTION Called without parameter, FDEV works as in the A733 and just clears all the data
(and the index area). The sizes of data- and index area are NOT changed. If the
optional parameter is given, it specifies the percentage of flash memory used for
index data. The default percentage is 33% (selected on very first startup or when
FDEV 0 is called). Additionally internal checks are made for the given percentage
and if it is too large or too small (depending on the Flash memory type) an error is
returned.
PARAMETERS None, or percentage of flash memory used for index area.
RETURNS The commands success or error code.
REMARKS GET/SET.
REMOTE Yes. But only the version without parameters.
EXAMPLE FDEV

INFO
DESCRIPTION Returns various status information.
PARAMETERS None.
RETURNS If no parameters are given, then INFO 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 (unsigned char)
• date as dd/mm/yyyy
• time as hh:mm:ss
• ver as x.x
• clk, stack and cop as decimal (unsigned char); they represent internal
housekeeping parameters: the A740 uses cop to number watchdog
occurrences, 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 A740 housing, which is device
dependent. The precision of the sensing element is low (±2°C), but it is
