… solved it myself by reading this exellent post by Arjan:

Best practices when sending GPS location data [HowTo]

When sending 3 bytes, we’re basically not sending the 4th byte of each integer, which should be 0xFF for negative numbers. Like for New York (40.712784, -74.005941, which would be sent as integers 407127 and -740059) we would send: For LSB: 0x573606 25B5F4 instead of 0x57360600 25B5F4FF (Least Significant Bit/Byte first, to match @JohanAdriaans’ encoding example above). For MSB: 0x063657 F4B525 instead of 0x00063657 FFF4B525. When decoding these 6 bytes back into two 32 bits signed integers,…
