OpenTX 2.2.0 problems

On my FrSky Taranis X9D+ OpenTX 2.1.6 the "Welcome to OpenTX" file is on the SD card at SOUNDS\en\SYSTEM\tada.wav. Delete that file and you don't have to hear that anymore when you power it up.

I just upgraded to OpenTX 2.2.0 to get Multi-Protocal support and the "Welcome to OpenTX" came back and there is no tada.wav. So I looked around and found SOUNDS\en\SYSTEM\hello.wav. That is the new one to delete.

Also, I am using the XSR s.port inversion hack for an F4 processor. Now that I am on OpenTX 2.2.0 it warns be ever 5 seconds that "Sensor is lost". For a split second the sensor is lost and it tells me about it every time. So I had to delete SOUNDS\en\SYSTEM\sensorko.wav also. My transmitter still buzzes when a sensor is lost though. So I will need to find another solution.

Most likely I am losing sensor for a split second because when I did the XSR hack I connected the non-inverted pad to the ppm pin. There seem to be ppm data collisions with the s.port data around once a minute. I didn't mind that tiny bit of unnoticeable inaccuracy but OpenTX 2.2.0 is pointing it out in a loud way. I reused the ppm pin so that I could easily move my xsr receivers between F3 flight controllers with inversion possible on all ports to F4 ports where secondary (after sbus) inversion for s.port is not available. So my F4 flight controllers are wired s.port to ppm and my F3 board are s.port to s.port.

I upgraded the OpenTX firmware on my Turnigy 9XR Pro and Taranis X9D+ in preparation for a iRangeX IRX4 2.4G CC2500 NRF24L01 A7105 CTRF6936 4 IN 1 Multiprotocol STM32 TX Module With Case that is coming in the mail. It will allow either transmitter to control my DSMX and FrSky receivers. If I had any toy quadcopters, they could control those also. Sounds pretty cool. We shall see.

When I purchased this on banggood I searched around for a while and tested many discount coupon codes. I finally found 13hot that gave me 13% off this product. Another one I commonly use is affiliate6 which gives 6% off of most items. I think these codes will cancel out my affiliate commission on my links (yes, I post affiliate links) but that is ok. Save some money.

I watched a great youtube video from Albert Kim on how to install OpenTX 2.2.0 at:

He explains and demonstrates things very clearly and doesn't waste time.
