Hi Andrew, thank you very much for this information! Please, can you post more Informations how you connect this module to the APM? I want to connect a Sparkfun Mate Silver to my Arducopter, but i found no Informations how to do that (and i don't want to damage my APM Hardware).

Regards

Markus

The sparkfun board will have a different pinout, but for these boards it is

 

APM     Bluetooth module

GND --- GND

5V  --- Vin

TX -- (resistor) -- RX

RX ---- TX

 

The module I bought came with a grey IDC ribbon cable with an inline connector on one end, and individual pin sockets on the other. This was handy because the pin order of the telemetry port is different to that of the bluetooth module.

I've used the same way when I had no Xbee. For now Xbee is doing everything and bluetooth module is going to my ardurover =)

Andrew, can you please share more info on how to change the baud rate ?

Comment by Roterdan Macedo on September 18, 2011 at 2:00pm

Hi all,

I already use one Xbee Bluetooth module. I only chage the Xbee module when I need to use the datalink in bluetooth mode.

I use this module http://www.dfrobot.com/index.php?route=product/product&path=45&...

@ Max:

 

Baud rate is changed by using an AT command - this must be done directly connected to the module, not over BT - so I just used the FTDI and some jumper cables. Also the command must be sent when the module is not 'connected' - maybe worth just un-pairing to be sure.

The command I used (using a terminal program like Hyperterm) was

AT + BAUD7

At that point the module would not talk to me any more because I had to re connect in the new baud rate of 57600. There is some more info on the link I posted - you may have to use google translate!

I bought 2 and a 1 amp wifi booster all for $40, hope they all work...

I have also orderd one.

Could I also use this this my android phone and the software for arducotper?

Comment by druckgott on October 15, 2011 at 12:41pm

And a second question: do I have to connect this on the telemetrie Port with an 1K resistion on the RX??? I do not understand exactly there I have to connect it??
