Jani commented on Thorsten's blog post u-blox M8N - ground planes, antennas and positional accuracy
Nice tests and intresting results!
Can you send your setting for M8N as u-center onfiguration file?
I have the cheapest M8N board (BeStar BN-880) on the market from BG and haven't got time to make proper settings for it. Like to try it and…"

Jani commented on Melih Karakelle's blog post iCELL Battery Monitor over Bluetooth Low Energy
"Nice idea! Few question came in my mind.
I also like to know the current consumption ?
Does it have any effect to battery balance? I'm quessing the current from balancer pins is very small like micro amps, but is it equal between pins?

Jani replied to UAVStuff's discussion Do you threadlock your prop nuts?
"I use "nyloc" nuts and without threadlock of course. I'm also changing nuts to new after 4-5 times opening. This habit comes from working with fullsize airplanes and copters....

Jani commented on Charles lakins's blog post Storm32 3-Axis Brushless Gimbal Controller
"Very nice! There's few similar designs now. EvvGC, VRBrain and this one for example. Wondering which has the best future with the firmware. Is there too big differencies between hardware for "cross" porting firmwares and GUIs?

Jani replied to u4eake's discussion APM 2.5 with NEO-6M ublox gps (not 3DR LEA-6)
"We should look what has been changed in AC3.1  AP_GPS_UBLOX and after that consider if need to change it for Neo-6M.
I made few months ago some testing to find out what config settings APM AC2.91b code actually overwrites succesfully to ublox.…"

Jani replied to Andrew Austin's discussion So Close!!! Quad motors not spinning, Afro ESC and APM 2.5: Please Help!
"Hi Andrew,
Double check your wiring, specially APM Output - ESC . I tried to look from picture, but can't say for sure if those are right. 3-wire cable from esc to APM should be in order:
-brown is ground and it should be on "bottom"
-red is…"

Jani replied to Xerravon's discussion is there any way to lower my HDOP
"Actually with UBlox it's PDOP we see in MissionPlanner and logs etc. Not sure why it is called hdop because it is not. See this issue:

Jani replied to Shane Veness's discussion log analysis
"I quickly looked at your log. I'm not expert, but found:
-You had GPS Failsafe and Fence enabled
-From log i can see you had one gps glitch error # 11 in 709 and multiple Fence Failsafe # 9 between 712-811
Bad gps data [# of SATS and bad HDOP] and…"

Jani replied to Randy's discussion ArduCopter-3.0.1 released!
Is APM 1 supported or even tested with AC 3.1?? I'm still using 2.91B and like to update when 3.1 comes out.

Jani commented on Brandon Basso's blog post Creating automatic mission plans for aerial surveying
"This is great and thx for posting!
I found one a small problem. If using Custom maps in MP Flight Plan window, GridUI window can't find those map tiles? After in-out zooming it finds Google satellite, but not custom tiles....
Regards Jani"

Jani replied to Jakey Boy's discussion APM 2.5 still won't arm my ESCs, I give up!
"Hi Jake,
Have you tried to connect one esc at the time directly to the receiver? Will it arm then? This will show if it is APM related problem or not.

Regards Jani"

Jani replied to Gabby Lang's discussion Neo-6m GPS no signal.
"Double check your wiring.
Also is the ftdi board 3.3V or 5V ?
I have one ftdi cable that connects ok and can read config settings from eeprom, but writing timeouts everytime. Still mystery to me, but i changed another ftdi board and it worked ok.…"

Jani replied to u4eake's discussion APM 2.5 with NEO-6M ublox gps (not 3DR LEA-6)
Do we actually need to have APM TX wire connected to gps? Simple solution to prevent APM overwriting gps setup is to disconnect tx pin, if we can use gps only in "listen" mode.
I'm also using NEO-6M from HK with APM1 + quad and have mixed…"
