I am trying to get data from the serial port. It appears to be sending a string but many of the characters are giberish.
I was following the work on this post viewtopic.php?f=97&t=6022&start=30. and tried to connect to the frsky dashboard app in the android market using a bluetooth modual with inverter but haven't hand any luck.
Does anyone else have experience connecting to this serial port?
I have tried an ftdi device with rx inverted, a rs232 usb serial port and have the same results.
Port speed is 57600 inverted from ttl.
Using putty to read the serial line.
when not inverted it fills the terminal with empty characters, when inverted, one line updates but the characters are not readable.
I would ideally like the gps data on the transmitter to be sent via bluetooth to the laptop/tablet.
Thanks for any interest.

Taranis battery compartment serial port
Re: Taranis battery compartment serial port
When the serial port is set to "S.Port Mirror" mode in the hardware settings it forwards all telemetry information received from the module.
BUT it is in "native" binary smart port format, not the old D-series format. AFAIK dashboard apps don't support it at this point, so you'd have to write a decoder, possibly based on the OpenTX code.
I think someone has already done that though, not sure if he's shared his work.

Some usb to rs232 converters won't like the voltage levels that Taranis gives on this port. It outputs 0 volts for logical 1 and 3 volts for logical 0. Have you read https://github.com/opentx/opentx/wiki/T ... erial-port

Thank you for the response. I think this is what I'm seeing, it makes sense. I will take a look around. I was happy to get the connection working over bluetooth with the module fitting in the compartment.Kilrah wrote:When the serial port is set to "S.Port Mirror" mode in the hardware settings it forwards all telemetry information received from the module.

I was treating the signal out as if it were 3.3volt. I did find a nice trick to change a setting on the ftdi chip to invert the rx line. located on this post http://diydrones.com/profiles/blogs/frs ... -ftdi-cabl this let me use one of the arduino boards as a usb serial port that was good for the low voltage.dinamich wrote:Some usb to rs232 converters won't like the voltage levels that Taranis gives on this port.

I followed this diagram and was able to put it all on the hc-05 bluetooth module and get it transmitting the same as the ftdi connection.
