I have to construct car that can move based on the result the code, so have to send byte of information by bluetooth(using the bluetooth module Hc -05) using python(currently using jupyter notebook, python 3). I've been trying for days with no luck. this are codes I've been using.
try with the socket library
for the hc05 is using the "COM4" or sending and "COM5" for recieving
HC-05 Arduino UNO
----- -----------
RX --> Pin 11
TX --> Pin 10
+5v --> +5v
GND --> GND
try with the socket library
import socket serverMACAddress = '00:00:00:00:00:00' port = 4 s = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_STREAM, socket.BTPROTO_RFCOMM) s.connect((serverMACAddress,port)) s.send(bytes("A",'UT AttributeError: module 'socket' has no attribute 'AF_BLUETOOTH'F-8')) s.close()And the serial and time library
import serial import time port="COM4" #This will be different for various devices,COM port. bluetooth=serial.Serial(port, 9600)#Start communications with the bluetooth unit bluetooth.flushInput() #This gives the bluetooth a little kick bluetooth.write(b"A")#These need to be bytes not unicode bluetooth.close() #Otherwise the connection will remain open until a timeout this is the 'C' code for the arduino
#include <SoftwareSerial.h> SoftwareSerial miBT(10,11); void setup() { Serial.begin(9600); miBT.begin(38400); pinMode(6, OUTPUT); pinMode(5, OUTPUT); pinMode(4, OUTPUT); pinMode(3, OUTPUT); } void loop(){ if (miBT.available()>0) { byte input=miBT.read(); if(input == 'B'){ //FORWARD ---- digitalWrite(6, HIGH); digitalWrite(5, LOW); digitalWrite(4, LOW); digitalWrite(3, HIGH); } if(input == 'A'){ //BACKWARD --- digitalWrite(6, LOW); digitalWrite(5, HIGH); digitalWrite(4, HIGH); digitalWrite(3, LOW); } if(input == 'C'){ //LEFT --- digitalWrite(6, LOW); digitalWrite(5, HIGH); digitalWrite(4, LOW); digitalWrite(3, LOW); } if(input == 'D'){ //RIGHT --- digitalWrite(5, LOW); digitalWrite(4, HIGH); digitalWrite(3, LOW); } if(input == 'E'){ //STOP --- digitalWrite(6, LOW); digitalWrite(5, LOW); digitalWrite(4, LOW); digitalWrite(3, LOW); } } }trying for days, i dont have a lot of coding skill.
