"This thread deserves an answer. :) I have been playing around with APM for years and just got my Phoenix 2000 in the air.
Answer to your question is no. It is not a good UAV. Fuselage is way too tight. Go with a Skywalker instead. Of Bixler if you…"

Failsafe and OpenLRS

HiGot failsafe to work perfectly with my Futaba 7C and 617FS. At signal loss it circled for 20 seconds and then come back in RTL-mode.But now I switched to OpenLRS and cannot get the thing to work. I…Continue
Problem with altitude logging

HiWhile analyzing my logs I noticed that there is a quite big difference between MixAlt and GPSAlt. Is this normal or can it affect the performance of my flights? I always had a wierd problem with my…Continue

HiI have been trying to get telemetry to work with my OpenLRS RX and TX. Been trying out different setups and baud rates but not got it to work. The transparent serial bridge is working perfectly but…Continue
Reset button (clears waypoints)

Hi I would like to understand more in detail what the reset button does. The manual (which I have read) says "Press the reset button to restart the board (you must do this every time you change the…Continue

Jesper Rooth replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"Glad to see that you guys are taking this further. Got less garage time now but just back into the OpenLRS world. Thanks for the work! Hope kha would bring this into the main code instead of more forks and another OpenLRS spinoff. openlrsng is…"
Andrew replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"Martin, you could also provide your mods to K4H, and he can include them (commented out by default) in the OpenLRSng trunk source code. People like me would then only need to uncomment your section for APM optimisation. K4H has done this in…"
Andrew replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"Great. Then I can send joystick commands through the RC uplink as necessary, rather than clogging the (minimal) serial uplink. This will not involve changing MP/APM, so could be a neat solution for MP joystick support. I have work to do... :)"
Martin replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"It would be very possible. In the current solution the Rx injects mavlink packets only, but the code is there readily available for the Tx side to use as well...

Martin replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"I branched out from kah's main branch right before he added support for CLI. Ie there is no support for setting parameters and such via commandline. I also made some structural changes to my branch, which I in hindsight regret (even if they…"
Andrew replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"In terms of using a joystick for camera control, might it be possible to modify the OpenLRS Tx firmware to replace RC axes 7,8 with PPM values received from the PC/joystick? I.e, I'm wondering if Tx module can inspect MavLink packets, and if RC…"
Andrew replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"Good to hear you've got such good performance with standard MP/APM. I'll give both of your OpenLRS branches a go as soon as I get a chance. Are there any compromises in terms of reduced OpenLRSng functionality? I.e, since you branched…"
Martin replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"I do not need to modify GCS_MAVLINK.pde inorder to reduce the send rate, the rate is automatically adjusted to maintain 100% link quality by the Rx (attached to the Autopilot) injecting radio mavlink packets into the data stream (exactly like…"
Andrew replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"Hi Martin, I'm curious about upload speeds with your branch.
Did you modify GCS_MAVLINK.pde in APM firmware, or do your OpenLRS firmware/settings handle parameter retrieve bandwidth fine with unmodified/release APM firmware?
Does your OpenLRS…"
Martin replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"Here's my take using OpenLRS hardware. It is a branch from K4h's firmware (which in turn is influenced by OpenLRS project).

I've got pretty good results in ground testing…"
Mike Machado replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM"I am thinking of taking on a project to do what you set out to accomplish. I am currently using FrSky and playing around with jd-IOBoard to get APM telemetry over the FrSky telemetry link, but want to use LRS instead. I have both an OpenLRS TX and…"

You just keep on truckin like you done before, now and in the future. Clones will come every now and then. See it as a proof that you are…"
Jesper Rooth commented on Melih Karakelle's blog post OpenBee: an OpenSource Telemetry Module with Xbee footprint"Nice work! Are there any benefits for us already running OpenLRS TX/RX's? Will this device improve the telemetry performance and if so - will it work together with OpenLRS since both are working on the 433 MHz band."
Jesper Rooth replied to Jesper Rooth's discussion Failsafe and OpenLRS"Fixed.
Changed the code on the OpenLRS RX so it only changes channel 3 (throttle) to the saved failsafe value. Works fine now."
