With Opentx2.2.1 you must push the power-button for 2 or 3 seconds before the X7 turn on.

Thanks great job
I have also opened the cover and there is no resistor on the rx-line. Unfortunately I do not have this tiny resistor, but I will get one.

Now I tried it without the battery but it does not change anything. The gps send the coordinates at 9600baud and send commands to the gps it not possible. These ublox7 are likely to be sold with a broken RX line.

Here is a picture of my two GPS.




The left one works well and the right one has the declared problem. Both are the NZ-GPS Version.

Can you also change the settings with u-center? I have a ublox7 too which does not work with oXs. It seems that this gps only send the coordinates but changing the settings (e.g. baudrate) is not possible. That's why it does not work with oXs.

Yes it works Thanks for the quick help.

I use the MS5611 and this is my config: // ***** 4.1 - Connecting 1 or 2 barometric sensor(s) ***** #define VARIO // set as comment if there is no vario //#define SENSOR_IS_BMP180 // set as comment if first baro sensor is a BMP180 or BMP085 (instead of a MS5611) //#define SENSOR_IS_BMP280 // set as ...

When I try to compile oXs with the alt-temp-compensation the compiler stops with this error message: exit status 1
'alt_temp_compensation' was not declared in this scope.
My arduino version is 1.8.1 and oXs 8.0.6

I mean the pin which transmits the serial data to the telemetry receiver (usually 4 or 2). Is this also tied to particular pin?

How can I change the TX-Pin to 0 or 1? If I try this in the oXs_config it came the error message "This PIN is not supported".
