Hi all,

Does someone know if a standard bluetooth adapter like HM-10 is compatible with kelly controller ?
The kelly bluetooth adapter really look like this one.. But it's 19 bucks instead of 1 on aliexpress and i already have one 😅

Thank you a lot =)
 
Hey Whitehawk, I have one of these Kelly BT modules, I'll try to take the plastic housing off and snap a few pics of the board this weekend.

Not sure about how it communicates or the protocols, but if the board is the exact same maybe the tx and rx is the same as well.

Will post results on Monday
 
Back when the KLS Controllers were in Beta a guy wrote that he used a random eBay Bluetooth dongle with the standard Vcc Gnd Rx and Tx pins.


I've never tried this myself though, as the dongles became available shortly after.
 
I have tried my dongle but it is not detected by the kelly app on android =(
 
Try switching rx tx maybe? Or you didn't pair it yet.

Unlike the Bluetooth BMS app, you have to pair the dongle with the Android system first. The app reads the list of saved Bluetooth devices, it doesn't scan for new ones.

If all else fails then I guess you will have to get the Kelly dongle.
 
You can try this (change the BAUD rate of the BT module) :

Prices are like $45 now. Would be awesome if I could use something cheaper. Wonder if it’s a matter of flashing the correct firmware on the bluetooth adapter…

I managed to do it with the HC-05 modlue a while back.

Ooo! Just match up the wires? Firmware? Got any pics?
 
Just like gba wrote a few posts up https://endless-sphere.com/forums/viewtopic.php?f=30&t=71942&p=1424739&hilit=kls#p1424739
You need some bluetooth modules and a usb ttl adapter like this:

I used the Tera Term program.

Good luck :D
 
I have a "Bluesmirf" from sparkfun connected to the 4-pin connector and it is connected to my phone and the "Acad"-app, I have a green led on the module indicating that. But, when I click "Read" I see following pop-up window:Screenshot_20220710-085758.png
Is that message about my bluetooth adapter, and what is wrong?
Baud rate is set to 19.200 which seems to be correct.
