The serial port on the X9D has inverters so provides RS232 compatibility. The power pin is also battery voltage.

The connections on the QX7 are non-inverted, and the power pin is 3.3V.

Thank you very much for the answer. Sounds like it could still be useful for hooking up something a bit more powerful and doing processing of telemetry data and such.

Here are files attached, you need to use this to program an arduino with and load the bootloader:
https://github.com/RedBearLab/CCLoader

Then use TI's SerialBootTool to flash firmware:

Hi all, I've ended up here in my quest to put Bluetooth in a jumper T-16 and wonder after reading through these posts if you guys can help.

The T16 has the pads and firmware support for the FrSky BT module and expects to see a module with the FrSky firmware on it.

The FrSky module is a RF-BM-S02 which can be had from various places for a fraction of the price of the FrSky branded one but they obviously don't have the correct firmware on them.

Is the post I've quoted referring to putting a bootloader and firmware on in the FrSky flavour or is it something else?

Is the FrSky firmware floating about anywhere that people know and has anyone successfully flashed a RF-BM-S02 module with the FrSky firmware?

Thanks, Steve.

EDIT: to clairfy, the T16 uses the Horus BT module and the module needs that firmware on it for it to work in the T16.

Is anyone able to help? I've done extensive searching and this is the only place over found the module firmware discussed!

The zip in the post you quoted has a firmware that FrSky posted at one point very long ago. Not sure if it has changed afterwards.

Ty for your reply.

So I'm right in thinking that it is a horus based firmware for the Bluetooth module, but a very old one?

As far as I'm aware, it's age does not matter, it's simply having the horus based firmware that matters.

I have a module on order and should he here from China soon, if I can't get it working on that firmware, a lot of T16 owners will be interested in doing the same :)

Another question sorry :/

I don't like to just ask and ask so I try my best to research solutions and I know that the bootloader flashing via arduino is done using the debug pads on the module and I know what pads are used but the next step is where I'm unsure.

When it comes to flashing the actual firmware, is it also done though the debug pads or others and what device is required for that flashing?

I'm assuming its not also done with the arduino as the code related specifically to burning a bootloader?
I have spi, St link, ftdi, pretty much every module I could ever need for flashing stuff but don't know which is used?

No, once the bootloader is on flahsing the firmware is done using the normal TX/RX pads, that's the bootloader's job.

Thankyou, so being on the RX/TX pads its a regular UART dongle I need to use then, nice and simple :)

I take it that the supplied program for flashing the firmware kicks the module into bootloader mode or is there a step required to put it into that prior to running the firmware flash tool?

Its possible that the module I receive may already have a bootloader on it, is there a way to find out or is it just a case of attempting a firmware flash and if it fails to communicate then go down the bootloader burn route or do you recommended doing it strait off the bat?

I'm really looking forward to attempting this, if it fails I've tried, if it works then I'm a happy bunny and I'll share my findings with other T16 owners and I'll owe you a very big thanks :D

Kilrah, i wonder if you can help me please.

After the first module failed to arrive and i got a refund, i ordered from a different seller and finally after months i have at last got a RF-BM-S02 in my possession :)

I have flashed a NANO with the CC loader sketch and i have figured out how to make the windows application work through the command line but now i cannot go any further as i dont know what pins on the RF-BM-S02 are the debug.

In preparation for its arrival i had done extensive searching and had found a pinout diagram that showed what pins were for debug and saved it to my pc but since then i had a major oops moment where i accidentally deleted the partition on the drive where the files were kept :(

as hard as ive searched, i cannot find the dam diagram which shows the pads for debug, i have found out what the 3.3v, GND, RX and TX are but the Debug pads are playing hard to get and ive trawled though scores of websites and 100's of images.

Can you help?

Thanks, Steve.

ok, i finally found the information i need, DD and DC are on pins P21 (DD) and P22 (DC) and ive successfully flashed the bootloader but i cannot get the Blemodule.bin firmware file to flash :(

I have tried two different USB UART modules and i get a 'response timeout' error.

any ideas please?

Steve.

Don't know, all I could find is I used my FTDI. Don't remember if this pic was of flashing the bootloader or the firmware.

Those are the rx and tx pads it's connected too so that will be the firmware and not the bootloader.

I have mine wired exactly the same but the serial boot tool just gives me a no response error :(

Maybe the bootloader is incorrect or didn't flash?

I used the file linked on this thread, maybe the file is wrong but it definitely flashed the bootloader :/
