Thanks"

Jesper Rooth commented on Trent at MyGeekShow's blog post A new Scratch Built Flying Wing: The Raptor"Hi Trent
I just crashed my second flying wing today (not beyond repairs). All done in EPS foam which is not perfect but ok for "short-lived projects". Bought a big EPP block which I will create my third generation wings from. I used Zagi10…"

But there has been progress on the OpenLRS side to push the limitations of the telemetry link. They got some more bandwidth at the tests but I…"

"telemetry rates are controled by the AP. the best i could suggest is to set them to 1.control-t just connects without getting the parameter list."
Jesper Rooth replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"Just timeout. No real message
I did try pressing CTRL-T and it actually worked. Everything connected fine. Getting 100% signal if only running telemetry rates for mode (and configured to 1). Adding HUD features got me down to 25-30% signal. I…"

Andrew Radford replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"Hmm I wonder if it is the initial request for all the parameters - What does the console say? Michael O will probably have to chime in. It would be great to get Open LRS working with the 'out of the box' software."
Jesper Rooth replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"Updated to latest version or APM planner. Setting very low values on the updates for telemetry did not make any difference. No connect. You could see that some packages were coming through but not enough to setup a stable…"
Andrew Radford replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"Great work! when you get something going well please do a blog post. For some people this could be a viable XBee alternative.
WRT Mavlink - the APM planner does request data streams at a certain update rate per second - this is exposed on the…"
Jesper Rooth replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"Success!
The OpenLRS transparent serial bridge as carrier of MAVLink protocol works. I ran QGroundControl instead of Mission Planner which had lots of more functionality and configuration possibilities regarding telemetry.

Jesper Rooth replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"I had another look at the specification for MAVLink.

I've been pondering on using the OpenLRS as a telemetry-only TX/RX so will be interested to see how you progress with this.
