TK102B - H02 - protocol - SOS alarm not received.

I am trying to make a TK102B (clone) device to send the SOS messages to the server.

GPS device configured properly. when updating position every 30 sec the server receives the string:

*HQ,865205030531940,V1,163507,A,4435.83898,N,02557.14277,E,0.00,0,030917,FFFFFBFF#

When the SOS button is pressed the server receives the folowing string:

*HQ,865205030531940,V1,163654,A,4435.83898,N,02557.14277,E,0.00,0,030917,FFFBFBFF#

I have configurent properly the notifications and I can see the device online/offline, device is moving and device has stopped, but no ALARM sos when the SOS button is pushed on the device.

If anybody has any idea how to make this function work it would be great.

Thank you.

SOS is supposed to be first bit of the status field. In your example first bit doesn't change. More info:
