bocorps commented on Patrick Duffy's blog post How to run a MAV-Link Heads Up Display on Android or Windows with HD video
"@Patrick, yes, for telemetry i use same setting as in MP : UDP and port 14550. Should i type something in MAV Connect or we leave it blank ? 
Besides, i did some flight test last week (with the version that need MP), video was all good in 48fps…"

"i can finally get video stream but even when i decrease resolution to 800x600 and framerate to 30fps, my phone cannot follow. Likely because cpu is a nvdia Tegra.One thing : For telemetry it still doesn't work.
@Patrick, one note : to make it work i…"

"@Patrick, i can connect my phone to the nano M5 using a static IP but right now neither video nor hud through application. I have let M5 in bridge mode, perhaps it is from that ?"

"@Patrick, Can you explain how do you plug your external antenna to your smartphone ?
I tried to plug my a nano M5 through an etho-usb adapter + OTG cable but the phone cannot detect antenna. I guess it is from the usb adapter that would need a…"

"@Patrick, i finally got 170watt at mid throttle, i needed to change subtrim to 40 so now i have mid at 1700us.Will be ok for manual mode but i have no idea if it will have effect on pixhawk auto mode (for that i will ask on opentx forum)."

"Hi Edwards, what do you think of this enclosure http://www.tekoenclosures.com/multimedia/manuali/pdf/TEK-CAM+.pdf
I already asked them if they plan to do a similar case for A+, they politely said no. But i think it is the way to do. See that also,…"

"@Gavin, last time i used http://www.online-stopwatch.com/ , you just point your camera to your display and print screen so we will see the latency. 

this 1MP 720p camera is quite cheap : Hikvision-DS-2CD3410FD-IW,  but it is not an upgrade to your…"

"@Patrick, i tried different battery and different esc, i always get +-7  130watt at mid throttle. I get nowhere the 170watt that you enjoy. I think it is something with radio setting (a taranis), i tried to reduce weight around 80% t be near common…"

"Should work in UPD also, manual is not clear about that but they do mention UPD somewhere.
price 150us. If latency is low, it could be interesting. If you buy one, please don't forget to report your test here :-)"

"i use UDP for both but depending what i plug first sometimes i will not get telemetry. Hmm.. Maybe it appears only when i use my laptop on battery so i will check that again."

@Patrick, yes am running on battery, anyway i changed power setting and latency is…"
