Mike, does this mean I will have to change the BT connection from COM3 to COM2 when/if the trainer over BT is implemented, or could I still use COM3 for that?

Thanks

Everything else is unchanged, this is just an extra option. I think it will be used if you have a different Tx module that handles telemetry, but you want the telemetry sent out over bluetooth to some other device (FPV?), and also want that other device to be able to send data the other way.
It's all just ways of routing data from one place to another.

This may help me get the BT trainer working as using it, I should be able to test commands to the BT module directly from my PC by routing COM2 to the BT module. This will make working out what I need to do much easier.

Great news.. Thank you so much..
Can't wait to testing the BT trainer ;) :) I guess my wife and neighbors will have to learn to fly whether they like it or not.. I will make sure they do.. :twisted: ;) :mrgreen:

Well I have been able to use the COM2<->BT connection to access the commands of the HC-05 BT module. With these, I have been able to 'discover' the BT module in the other 'PRO, and even find its name. So I have the HC-05 running in 'Master' mode.
So I should be able to come up with commands to find it and bind to it to enable communication.
I'll need to implement a 'bluetooth search' menu for discovering devices, so you can select one to which you wish to connect.
I think the module does keep a list, but I think I should keep the list myself. I'll put this list in the general radio settings.

For each model I think we need a "bluetooth role" setting (master or slave), and, if master, the bluetooth device for connection.
I also need to extend the "Bt Type" setting to include NONE for when there is no module fitted.

Slow, but some, progress!

Thanks Mike.. that is great.. From your previous post, I understand both COMs 2 and 3 will work the same? At least for trainer? So, it will be just a matter of selecting the right COM port in the fw?

That's great news, I look forward to testing it. I had to switch back to DSMX until I can sort out antennas for my openlrs system and get back to testing bluetooth, but i expect it will work fine with mavlink.

so where do i get the code to add the bluetooth as a slave trainer only. I'm looking at doing a arduino head tracker and i want to bluetooth the three channels to my 9xr pro. is that something that is possible at this point? next question would be what type signal would i need to transmit over the bluetooth from the arduino?

thanks

Just adding that you can get a cable for the com3 socket at sparkfun, part number PRT-09916. Seems to fit fine and my HC-06 is working to forward the telemetry stream.

Bluetooth Control Module?

Post by jimichunga » Wed Sep 23, 2015 9:05 pm

[Forgive me if this has been discussed, I searched this thread & site as well as google and could not find any pertinent information.]

I have a Flexbot which is bluetooth controlled via an app. My question is can the Taranis (w/ Bluetooth module) be used to control this little guy?

No. Supposing the connection was possible (haven't checked details) the specific control protocol would still have to be implemented.

This may be a silly question but other then linking two transmitters together for training does adding a Bluetooth module to a 9XR PRO have any function? This is not a smart aleck question, I'm new to the radio and plan on adding Bluetooth to my Pixhawk and CC3D for tuning and mission uploads in the field and I saw where the 9XR Pro has a Bluetooth socket and was wondering what or how it could benefit me. I'm also curious about the encoder and it's function but I thought I would hold off on asking two silly questions at the same time. :-) Thanks in advance.

Cheers,
Tim

A Bluetooth module has two/three other functions currently available.
1. Transmit the raw telemetry data over bluetooth.
2. Receive SBUS data from the eepskye simulator. This allows eepskye to actually control the servos normally controlled from the transmitter. Quite useful when editing a model on eepskye and wanting to check it works with the target model.
3. A feature I added mainly for getting the bluetooth module to work, a transparent data connection between COM2 and the bluetooth module. This might be useful if you have serial data coming in on COM2 and you want it sent out over bluetooth.

The encoder inputs allow you to add a rotary encoder (with switch) to provide an easier method of editing on the radio. The biggest problem is mechanically mounting the encoder, often this is done by replacing one of the pots with the encoder.

MikeB wrote:I've managed to get a HC-05 module installed in a 'PRO, and I have modified the code to make it start to work.
The connections are from the COM3 (Bluetooth) connector, 0V to 0V, 3.3V to 5.0V (erring on the side of caution), Tx to Rx and Rx to Tx. In addition, I have wired the ERASE signal to the KEY input. The HC-06 is physically located in the battery bay. I'm using a 6-cell NiMh pack, and this leaves an area on the right, not covered by the bay cover, for the module to be in.

With this setup, and the HC-05 still set as a slave device, the code successfully changed the baudrate to 115200, and then I enabled the "BT as trainer" option and successfully got data from eepskye on the Trainer menu.
I have also successfully routed telemetry data to the PC over the BT connection.

So I reckon support for both the HC-06 and the HC-05 is working in slave mode. This makes it worth installing a HC-05, ready for further enhancements.

hi mike ive just got my hco5 bluetooth, do i need to cut tracks on vcc or can i just connect wires to headers normally, as the cut header post i saw was for extreme board but i do have the same bluetooth modual thats in that post, my bluetooth needs 3.6 volts min and six max will the
vcc supply enough power from pin on board, plz could you give me a step by step as i have no idea on how to set up modual to be ready for install, any help much appreciated idar

I run my BT modules (HC-05 and HC-06) in the 'PRO from 3.3V. I believe, the BT part itself runs from 1.8V internally.
For the HC-05, you need to connect the COM3 connections to it, crossing Tx on the PRO to Rx on the module and Rx to Tx.
You also need to connect the signal ERASE (only used for that at power up), to the "pin 24 34" on the HC-05.
The first post shows the COM3 connections. A few posts later a post has a link to a diagram showing where the ERASE signal may be found.

hi mike thanks for help heres a pic of my modual download/file.php?id=11344&mode=view
download/file.php?id=11345&t=1

plz can you take a look and tell me what i have to do to get running, ie do i copy what is pics above ie cutting tracks etc as the only thing i can see ive done different is i have not cut tracks and i have not soldered erase to the little button i have just plugged erase into the pins, i did unsolder the pinss and turned around so modual arieal faced out as ive fitted inside on other side of battery just like in photo in this forum, im really wanting to get this working so id really appreciate your help, thanks idar

Oops, a typo, I meant pin 34.
You look to have seen João's description of how to mod the BT module, since you have got a picture from his 9Xtreme description.
You need to do the same mods to your module, then connect 3.3V, ground, Tx and Rx as I described and the ERASE signal to the pin labelled 'To 9XT pin "PA5" '.

r217 does support the BT connection I believe, although going here: viewtopic.php?f=7&t=4676#p65894, and downloading and installing ersky9xr_rom.bin from ersky9xProvR218h.zip will get you the most recent code for BT.

Reading the last posts (and maybe I have missed it) I still don't understand what radio you have..
The 9xtreme has 5V readily available and is where I connect my BT module's VCC pin.
For the 9xtreme you need to look in the "my 9xtreme installation" thread. I will post a link here when I get to my PC.
You do need to cut that little track if you want to use the "EN" pin on the BT module. It might be possible not having to cut the track, but you can't use that pin.

hi i looked at where you say to cut but my modual does not have a line going from vcc to en my bluetooth has same writing as one in jaoao post but my track thingees look abit different do i cut a little line through the vcc one, ill post a photo if i can, thanks for your help its been great, i ended up soldering a little wire between pin and little botton, i cheaked with muilti meter and it follows to pin 34 once the wire is there, so i hope thats right, now to work out where exactly to cut on my bluetooth modual then i should be away i hope

This one is definitely different from mine even if the markings are the same..

Please post some good resolution pictures from the front and back of the module..

I don't understand, You just posted photos showing that your module doesn't have the little track.. So, what track do you want to cut then? :o

Please do post good pictures of your module.. Both sides..

One of the pushbutton pads should already be connected to pin 34. see picture
