Hi Ian, good news for you.
1) B500 Temperature: It seems the code just didn't exist for this device. I've added the temperature parsing code a few minutes ago. 2) B500 Baro Altitude: Borgelt doesn't use the usual PGRMZ sentence for baro alt and that's why it thought it didn't have data. I've added alternative parsing of the baro alt for the BorgeltB50 driver. However I wouldn't use this feature, since Borgelt only sends full hundred feets rounded up. So if you are on 123 feet you will get 200 feet displayed inside XCSoar. That's what we get from the device and since we can't do magic we can't show you anything more precise 3) B500 TAS/IAS: The indicated airspeed was also bugged. I've fixed it too. Conclusion: Please wait for the next build that Max does and try again with that one.
