T9x and bluetooth

[nickxab]

Guys is it possible to add a bluetooth module on the stock 9x board ?

[Kilrah]

What for?

[nickxab]

for telemetry on the android...if it's not possible then is it possible to solder it on the DHT module ? cause i found a tut about adding BT module on the DJT/DFT http://flitetest.com/articles/Adding_bl ... try_module but i don't know if i can do this on the DHT....

[Kilrah]

The easiest is to connect the bluetooth module directly to the frsky module, in parallel with the 9x (TX only).

[nickxab]

So it will work with the DHT, right ? yes Tx only i know

[Kilrah]

DJT, DFT, DHT are all identical.

Oh i see ! and one more thing....do i need a TTL converter for this bluetooth module ? http://dx.com/p/wireless-bluetooth-rs23 ... -844080711

[Kilrah]

It says TTL level, so yes.

There are some detailed infos here, and also links to a module that doesn't require one:

So in my case i use the Option 2: inverting the signal using FUL-01

I know this is old but did you manage to hook a BT to the original 9X?
