Just bought a QN-BM bluetooth module for my Quadrino.
Using EZ-GUI Ground Station to talk to it (Have also tried Multiwii Configurator app from Play Store)
I can connect to the Bluetooth device no problem with both apps.
The problem is that I don’t seem to be passing any serial data thru the connection either way once connected
The card says to use 115200 baud. I have tried that along with every other available baud rate down to 9600 on the Quadrino.
I have tried both serial UART ports (1 & 3) with no luck.
The green power LED is on steady.
The red blinking LED goes solid RED when the Bluetooth connection is established.
Can you attach some pictures showing the wiring of your bluetooth module to the Quadrino Nano ?
It could be a simple issue of wiring or baudrate as well but let’s take a look at the wiring first.
Maybe, but everything is possible even a problem with the cable itself so a picture would help diagnose.
MultiWii will not care about the serial port you choose but the Baudrate can be changed in the FCT for a port in particular. The Bluetooth adapter should be in 115 200 so set them all to that.
I will take a picture tonight.
Yes, I understood either port should work.
I started with the 115200 on both ports and then tried every other baud just to be sure.
Those bluetooth modules should be programmed in 115200 from factory but that’s a posibility to be aware that they could be at another baudrate.
But first the wiring…
Yes, I pressed in the connectors multiple times.
I also checked for bent pins in connector.
I reflashed the board with the baud rate multiple times.
I am a software engineer and understand how this works.
Have you personally tried this combination to be sure it does work?
Once connected, you get the Green and Red LED’s steady ?
One thing you can try is to create a new profile in the FCT and go directly to the flash page and flash, this should work.
If not, then the bluetooth module could be the issue and/or the wiring.
Sometimes the pins in the white connector could have been crimped on the plastic isolation rather than the wiring. If you are able to verify that might be fast.
Otherwise we will look at getting you another module.
Yes, the lights are steady when paired. This was mentioned in my very first email.
I have an idea, How about we stop wasting time with this defective BT module/cable and you send me a new one.
We’ve wasted far too much time with such a simple connection already.
We are sorry for the delay but most of the time things can be resolved by troubleshooting.
This to avoid shipping replacement to end up in the exact same situation.
You can create a Support Center Ticket with a link to this forum post, our RMA team will handle this.
To speed things up, can you provide your shipping address in that message as well ?
