New features in firmware v. 4.73 Large
Released: April 21, 2005.
 

Firmware v. 4.73 was released prematurely due to a minor problem that has been discovered in firmware version 4.72
The problem discovered in v. 4.72 is in the Set Real-time clock / Get Real-time clock transactions used when Setting/Getting the clock externally over Cable, CSD or GPRS.
The problem discovered  is that the time/date is set incorrectly in the unit. The problem can be demonstrated in the RTCU IDE in the "Adjust clock" dialog.
Applications not depending on external clock management will not be affected, so an upgrade is therefore not necessary or recommended.
We are sorry for any inconvenience.

	Enhanced recovery of Siemens MC35i GPRS lock-up problem experienced in some networks.
	DeepSleep() will now degrade to a normal Sleep() operation when the unit is connected to the RTCU IDE

RTCU D4,A6 and A5 (Small) version 4.52:

	Support for logGotoLinsec() on small RTCU units included.
	Query of GSM parameters is now unblocking during initial startup of unit.
	gsmMakeCall() problem where the caller hangsup immediately and the unit still indicates a connection has been fixed.
	gsmHangup() can now interrupt gsmMakeCall() during the dialling phase.
	serFrameReceiver() bug fixed where only sizeof buffer-1 bytes could be received when running in framed mode.
	D4 Display. displayXY() changed to better enforce the physical dimensions of the display.
	Persistent memory operations are now fully async safe.
	New function to retrieve the SIM card number: gsmGetICCID().
	SMS messages can now not be send during a CSD session. This is to avoid problems with the IDE communication.
	Optimized driver code for Flash/FRAM access. Now upto 10 times faster access!
	New real time kernel implementation with much faster taskswitch and less overhead.
	PowerDown() will now return to the applikation with an error code if powerdown is not successfully.
	Fix for negative return value in logGetNumberOfRecords() and logGetMaxNumberOfRecords() when value > 32767.
	DeepSleep() will now degrade to a normal Sleep() operation when the unit is connected to the RTCU IDE

Small (SA,DIN,M7,D4,A6,A5):

	Enhanced implementation of PIN code handling.
	Timed Network Query (CREG?) every 10 mins.
	On the A5 boardSupplyType() will return DC when supply<18V, and AC when supply>=18V.
	boardGetProfile() now extended to return number of serial ports.
	Size of VPL code-segment raised from 64 Kbyte to 128 Kbyte!
	Better precision of real time clock when using DeepSleep.
	During DeepSleep it is now ensured that the system LED's are off to save power.
	Support for using the RTC build into the GSM module on the RTCU A6 target

Large units (A9i, M10 and M11):

	Enhanced implementation of PIN code handling.
	Timed Network Query (CREG?) every 10 mins. Recovers from problems in some networks with bugs in GSM base stations.
	sockSetTCPIPParm() introduces 'Authenticate' parameter. Did not work in 4.60, now fixed.
	boardGetProfile() now extended to return number of serial ports.
	gsmGetProviderList() / gsmSetProvider() can now be called during a datacall or GPRS session.
	Support for the on-board battery charger on RTCU A9i
	Better precision of real time clock when using DeepSleep.
	During DeepSleep it is now ensured that the system LED's are off to save power.
	Bug in gpsPosition / gpsInfo fixed when moving west of longitude=0.
	On the A9i the GSM module is not automatically powered up by the system to support low-power applications.
	Support for the RTCU M11 series.
