What is the smallest OpenXSensor vario one can build?
Which Arduino can be used?

Just back home from flying the Dogfighter. Without GPS. It did not get a good GPS fix. Sensor lost constantly. No room to place the GPS farther away from the RX in a dogfighter. Even shielding with alu foil did not help in this situation. We need further testing to find what is wrong. At home I conn...

Am I correct that you only placed a metal plate between the RX and the GPS and connected that plate to GND. You did not capsul the RX or the GPS? RX and GPS already have a common ground, which now the plate is also connected to. There is definitely more data needed, i'm looking forward to your resul...

Still strange: I get good communication and fast GPS fix in U center with GPS connected to FTDI. But still have BIG problems getting GPS telemetry when connecting GPS to Arduino and RX. I remembered reading this post: http://openrcforums.com/forum/viewtopic.php?f=86&t=7562&start=390#p126943 ...

The one I bought from Aliexpress is terrible.
Made my gear ready for tomorrow. Tested the GPS one more time.
No fix in open air after 5 minutes.....
This one will go in the bin.

Opened a dispute and will get full refund and buy a new M7 or M8

BUT WHICH ONE ??

1) The GPS has two leds. One for power one for satellite fix. When GPS has a good fix, the green LED starts to blink. oXs does not send data via Smartport before GPS has a good fix 2) I would strongly advice NOT to buy the GPS I have. I realy think it's counterfeit/fake. - the QR code does not corre...

After a lot of testing Michel found a solution: We changed following entries in the oXs_config_basic. h #define FIRST_BARO_SENSOR_USE NO_BARO // select between NO_BARO , MS5611, GY86 , BMP085 , BMP180 , BMP280 #define ARDUINO_MEASURES_VOLTAGES NO I did not need these sensors to be used. This is a GP...

okay great .
Thanks again.
I will send you a PM with my emailaddress

still no luck with the extra 22k resistor

I just made a unit with a new Arduino.
Still the same problem. No GPS sensors found.

I did not add the 10k or 22k resistor yet.
I have 10k and 22k resistor. What is best?

Do I understand correctly that you want me to test this (adding purple resistor ???):

I could not wait, so connected it all up. It still only shows the RPM sensor (ID 5) from the Arduino + RSSI and RXBT (ID 25), but does not show any GPS sensors. So I took a plane in which the GPS sensors (ID 4) were already discovered when using the FrSky GPS v1. Connected the Arduino. But also only...

FrSky Smartport

I will try conencting to X8R receiver again late this afternoon
Thank you very much so far!!

Readable characters. Going on and on. Does not stop

See attachments

More info screens from u-center about NMEA and port settings

Yes, the unreadable code continues. Does not stop.
I tried all the different baudrates. Same unreadable symbols.

See attachment in 9600

The GPS has a fix.
The green GPS light blinks.
I have waited more than 5 minutes after led starts to blink

Test 1) it continually spits out $GNGSA, $GPGSV, $GLGSV, $GNGLL, $GNRMC, $GNVTG code including GPS LAT/LON data
Test 2) lots of unreadable code, see attachment

I think you mean CTRL+SHIFT+M? This is what is displayed: openXsensor starting.. milli=0 freeRam=523 Enter setup voltage Reference voltage:1100 Voltage:1 , pin=6 , offset=0 , mVoltPerStep=17.92 Voltage:2 , pin=8 , offset=0 , mVoltPerStep=2.01 Voltage:3 , pin=8 , offset=0 , mVoltPerStep=3.44 Voltage:...

Perhaps that you module has such a config. So if e.g. the GPS baud rate is different from 9600, it will not recognise the commands sent by oXs. Using Ucenter program (free) from Ublox, I expect that you should be able to find the config of your module at power on and to change it to the default Ubl...

As mentioned here http://openrcforums.com/forum/viewtopic.php?f=86&t=10691 , I received my M8N (fake?) GPS module. I connected it to u-center and it gets a fix position. Unfortunately I can't get openxsensor to send the GPS telemetry to the FrSky smartport. The arduino 5v 16M is programmed. I al...

I just received my M8N Ublox from Aliexpress. I think it's fake / counterfeit. What do you think? I contacted the supplier, as he told me that it was a genuine M8N and firmware was updatable. lets see what his respons is. I will wait with adding the URL and the Alieexpress supplier name until we kno...

Any one who bought a working M8N GPS from alieexpress?
I'd like to have a link of a version that is known to work properly

Thanks

I'm new to openXsensor and just got my Arduino Pro Mini 5V 16Mhz working for RPM telemetrie only. Two questions: 1) Do I need a 5.6k resistor between the smartport wire (going to the RX) and the PIN 4 on the Arduino. I get conflicting information. I use the 5V 16Mhz Arduino. Arduino is powered by 2s...

Turned on X9D Haptic goes ON and a beeping sound. Went into Model memory. It only had one (default) model Copied the model from MEM 1 to MEM 2 Haptic and beeping stopped. Erased MEM 1 Copied MEM 2 into 1 Deleted MEM 2 Everything is fine. So without any changes, the haptic and beeping stopped just by...

Radio: FrSky 9XD Plus Firmware 2.0.9.2 mode 2 Everything fine until I charged the stock battery with the stock charger. I charged the battery overnight until the green light was off this morning. Then I unplugged the carger. This evening I powered on the radio. After some of the switch warnings, the...
