Setting up Bluetooth (BLE) communication between Arduino UNO and Laptop running Linux

Question

I have a bluno (arduino uno with a built-in BLE[TI CC2540]) and laptop (ubuntu) with a built-in Bluetooth module.

I want to make a Bleutooth BLE communication program between arduino and linux.

I want to send data from linux to arduino.

Any help would be awesome!

Answer 1

And where exactly is your problem respectively at which stage is your development currently?

In general: You have somehow to talk with the bluetooth module on your linux system (Raspberry?). For this you need e.g. API-calls to give and read command from you bluetooth module. If there are no read-to-use APIs then you need to write it yourself, reading the manual of the module and communicating with it using SPI, I2C,...

After a successful hardware-communication with your bluetooth module on the linux system, you have to communicate with the BLE module. For this developing a protocol with cyclic redundancy checks,... would be a good idea, insted of sending plain "chars".
