Re: [Paparazzi-devel] downlink only

[Martin P]

Hi, 

I do not intend to do any settings via the transmitter. 

However, I do not seem to have 2-way-communication via the modems. Although I 
saw something with the scope, I am not able to use neither the settings tab in 
the ground station nor the settings dialog from the tools menu. The latter 
shows an empty window. 

On the field I used a modified flight plan which does not stop at the holding 
point. First of all, uplink seems not to work an secondly, most of the time I 
am alone on the field. 

Usually, when ground testing, the throttle reacted to the stick in AUTO1. 
Yesterday I switched to AUTO1 and the plane throtteled up and took off before I 
expected (I use a landing gear). Switched to MANUAL and climbed, then back to 
AUTO1. No throttle. Probably this is because I put the vmode="throttle" in the 
takeoff block to get executed anyway. 

I havent't seen any vmode statements other than specifying "throttle". What are 
the valid values for vmode? 
Could I automaitcally set the vmode to pitch in AUTO1? 

Managed to land manually, in spite severe radio interference. Radio 
interference in spite having changed the receiver cable to a shielded wire. 

So, I am still struggling and learning. Every help is greatly welcome. 

Greetings, Martin
