Malfunctions in firmware 1.5.3 and 1.5.6 in alarm mode and other issues

[micha06de]

Unfortunately, firmware 1.5.3 has some serious errors:

1. In alarm mode, the tracker sends packets every 15 to 20 seconds, regardless of the value set for AT+ATDC, this will certainly violate the fair use guidelines! This bug is fixed with version 1.5.6.
2. The alarm mode is not terminated after one hour as before, but remains active until manually terminated, this issue also exists in version 1.5.6

Furthermore:

• The value for the long press of the button to trigger the alarm, which is set via AT+EAT, has been changed from seconds to milliseconds, although the manual has not been adapted. In addition, contrary to the description in the manual, 2 s (2000 ms) instead of 5 s are now preset.

• The help for the AT commands that is output at “AT?” contains incorrect descriptions of the commands, e.g. “Enable/Disable LED activity for uplink” for commands that execute something else:

AT+LON     : Enable/Disable LED activity for uplink
AT+CHE     : Enable/Disable LED activity for uplink
AT+CHS     : Enable/Disable LED activity for uplink
AT+NMEA353     : Enable/Disable LED activity for uplink
AT+NMEA886     : Enable/Disable LED activity for uplink

• As of version 1.5.3, the changelog states: “Change the sleep state, you can sleep for a long time, such as 4 hours, 24 hours, etc.” but does not explain how to set this.

Please fix the errors and adapt the manual and Wiki to the firmware changes.

Hello, is there anyone else here who can help me?

I'm using version 1.5.6 and my alarm auto-cancels after 60 alarm messages are sent. Theoretically that could be one hour if ATDC=60000, but in practice I've found it takes closer to 2 hours because of the additional time required to acquire a GPS signal each time the alarm is sent.
