VEX Cortex talking to Python PySerial

So I am trying to get a Pc (well mac) and a Cortex talking to each other over BT using a UART port. The connection is connected but transferring data is just garage. I am using the https://github.com/JMarple/BNSBluetooth framework

RobotC Code


#pragma config(UART_Usage, UART1, uartUserControl, baudRate38400, IOPins, None, None)
//*!!Code automatically generated by 'ROBOTC' configuration wizard               !!*//

#include "BNSlib_HC05.h"

task main()
{

	setBaudRate(UART1, baudRate19200);
	char myString[10];

	while(1==1)
	{
		bnsSerialRead(UART1, myString, 10, 200);
		writeDebugStream((myString);

		delay(500);

	}
}

Which prints out values like f~øø€x€ø10.000000˜øøxøø€x€ø10.000000

The PySerial code is ( i have also tried .encode on the string)

import serial
import time
count=1

ser = serial.Serial(port='/dev/tty.HC-05-DevB', baudrate=19200)
print("start")

print("connected to: " + ser.portstr)

while True:
    ser.write("1234567890") 
    print("sent")
    time.sleep (500.0 / 1000.0);

ser.close()

print("close")

I put it on stackoverflow if that encourages anyone http://stackoverflow.com/questions/38805018/serial-communications-between-pyserial-and-vex-edr-cortex

The HC-05 was not configured correctly and so chucked out junk!

Okay as long as it is working now. I didn’t see anything wrong with the code and was gonna get out my cortex and hc 05 to do some testing this weekend.
