MPX Protokoll GPS - Alt, Heading, total Distance

[Astor87]

Hi mstrens, I just started my oXs_on_RP2040 this weekend following the German RC-Network Thread. I do only use MS5611 for Vario and an BN-180 for GPS data. Everything works absolutely perfect on an FrSky protocol with RM R168 via FrSky S.Bus with actual SW 2.1.4 However I do use MPX receivers for 99% of my models. Switching the protocol is really simple. Unfortunately there are currently only 3 GPS parameter transmitted, GPS Groundspeed, GPS Home bearing, GPS Home distance if I am right. And this is totally clear for me consulting your file: "fields per protocol.txt" Reading a previous issue #40 here from Pierre and all 69 pages on RCG I understand that Position, Date and Time or Sats cannot be transmitted. On Arduino oXs there are 5 parameters. The 3 transmitted plus GPS Altitude and GPS Heading.

Would it be possible to add these two parameters in your MPX protocol transmission list ? And finally would it be possible to calculate total "flown" distance as a summary function of speed over time (maybe in m or km) ? I would assume that could be interesting for all protocols.

Sorry this shall not appear as a complain or issue at all! I really do highly appreciate your great work and effort on this great project!!

I added GPS alt and GPS bearing to Mpx protocol in version 2.2.0.

For cumulative distance, it requires more work.

I also added now in 2.2.1 cumulative distance to sport and Mpx protocols. The code is not tested. I hope it is OK.

Many Thanks ! I just loaded 2.2.1 (test) on the RP2040 Zero. With FV I can see the new Gps cumulative distance added. I could not find the GPS Alt, Heading, Cum. Distance on Sensor Search but I used my RM TX12 with a IRangeX Multimodule and MPX Protocol. I will check tomorrow with with my RM TX16S and Original MPX HF Module and further with my Zorro 4in1 . Will also test with Frsky Sport. Will keep you posted - I am sure it will work ! But anyway you are doing a miracle job !!! Really great !

I think I found a bug for mpx protocol. I made a version 2.2.2. please continue your tests with this version

Will do, but I am currently underway and will be back home this evening. Keep you posted!!

Hi mstrens, just being back home I loaded 2.2.4 RM Zorro with Frsky X Protocol and RM 168 S.Bus all data available incl. Cumulative Distance! For me all ok !

on M-Link Protocol : today RM Zorro and yesterdays RM TX12 with IrangeX 4in1 (which failed) now both transmitter read and show the 3 additional Data: GPS Heading, GPS Altitude and GPS Cumulative Distance. Flight Test for cumulative distance will be done after this heavy rain here :-) Superb Job and for me great !

Just one more comment if I may: In M-Link Protocol: GPS Distance from Home i.e. Index = 13 is transmitted in "km"
Wouldn't it be more logic to transmit GPS Distance from Home in "m" ??? A Model should be always in sight which is 90% less than 1km - at least for me. Just a thought.

GPS Cumulative Distance i.e. Index = 12 is transmitted in "km" for me ok

Again many thanks for your great Job !!! BR Wolfram

Sorry it shall read : RM Zorro with Frsky X Protocol and RM 168 S.Port !!!!!!!!!
