  • Moates Ostrich and bluetooth connectivity

    Im starting another project today, i got 2 of the HC-05 modules off of ebay for my ostrich's to install into and test. i will post my findings and discoveries along with if these are successful a guide on how to install the bluetooth modules and configure your computer. i have added pictures of the bluetooth module i have chosen to work with and a picture of the bluetooth module headter on the ostrich main board.

    so far the first issue i have found is the the TX and RX pins on the bluetooth module are flipped compared to what they are on the ostrich board so i will be unsoldering the header pins off of the bluetooth and using like strands of copper wire out of an ethernet cable to connect the bluetooth module to the ostrich. i will most likely hot glue the bluetooth module to the ostrich main board to keep it from moving or shorting out on any other hardware. i dont know how much of a toll this will take on the ostrich's battery but i guess i will find out in time. on the battery i had another thought since the battery is lithium ion to see if its possible to pull voltage from the chip header and charge the battery or even use power from the chip header to power the bluetooth module. bluetooth module requires 3.6v to 6v so if there's 5v at the chip than a jumper wire from the input header of the ostrich ribbon cable to the power pin on the bluetooth module could allow it to easily power the bluetooth module directly from the ECU.
    HC-05 master/slave bluetooth module. Bluetooth module header is on the far right.

    i did some testing with this bluetooth module and had negative results so far. i cannot get connectivity with tuner pro. i think there's a com port issue that i will have to resolve but it should work.

      A serial connection can be more than just wiring Rx/Tx. There are some handshake lines which may be used (like DTR, DTS...). You should read the Ft232RL datasheet and have a look if any of this lines is used on the PCB.

        i will have to look at that chip, thank you. havnt had time to work on this part specifically lately but i will be working on it more over the weekend.
