Bluetooth Shield Seeeduino

Products & Technology Bee series & WSN
#1

Hi y’all,
Good morning for ones who have some sun and evening for the others. :slight_smile:

I’ve encountered a problem with my two Bluetooth Shields that I’ve purchased on the Seeedstudio website.

I’ve followed the instructions on the wikipage to make them communicate but it doesn’t work and I cannot sleep since one week :frowning:
Plz HELP

Despite of all my efforts, the green LED blinks always twice a second.I’ve also bought a packet sniffer from TI to check if there is any transmission of the bluetooth signal but is not :cry:

What solutions can you provide PLZ
anything is welcomed!

Thanks and have a good day

that’s is the code I also tried to connect with the CC2541 sensortag from TI:

[code]/*
In this code, we are goin’ to test
the communication between one Arduino Uno Card and the sensor tag
through a bluetooth connection

This code is uploaded in the Master Board

//Pins 2 and 3 defined as RX and TX
#define Rx 2
#define Tx 3

//On crée un objet blueToothSerial pour utiliser l’Uart sur les broches RX et TX
SoftwareSerial blueToothSerial(Rx,Tx); // RX, TX

//Variable which contains received data from the Bluetooth link
char received = ‘0’;

//Buffer which contains data received from the terminal
String received_terminal = “”;

//Buffer which contains data received from the Bluetooth link
String received_bt = “”;

//Declaration of the buffer of reception
String received_buffer="";

//Boolean variable which turn into true if
//Something has been read
