Solar radiation not reported #7

Hi,

I'm using the radiohm_trp.ihx firmware and the packet sent by the ISS are correctly decoded except the solar radiation data. I'm using an official Davis pyranometer and I'm sure it works, but the reported data says 0.0 constantly.

Below an example message: { "transmitter_id": 0, "RSSI": 131, "recv_packets": 32133, "lost_packets": 35, "bad_CRC": 12, "wind_speed_mph": 9, "wind_direction_degrees": 188, "temperature_F": 40.66, "humidity_pct": 79.3, "UV_index": 20.44, "solar_Wm2": 0.0, "rain_spoons": 41, "raw": "80 09 85 19 1B 00 1F 5A FF FF", "version": "1.0" }

I'm also wandering whether the UV data are correctly decoded. I have no UV sensor connected to the ISS but a value of 20.44 is always reported.

Compiling radio~hm_trp.ihx from source solved the problem. Now the solar radiation is correctly decoded.

I Initially downloaded radio~hm_trp.ihx from http://uav.tridgell.net/DavisSi1000/firmware but I guess that the decoding of the solar radiation was not implemented yet at the compiling time.
