CC2541DK-MINI: Help with CC2451/2540 bluetooth communication

Part Number: CC2541DK-MINI
Other Parts Discussed in Thread: CC2541

Hello, 

I buy a Kit dev mini for CC2541 and i have been successful with all step that are teach on the CC2541 Mini Development kit quick guide. I do the test of the button from key fob, the accelerometer, and the buzzer test. Now i have to do a test that are a little more simple. I need to do a conversation between the CC2540Dongle and a Android/Aplle cellphone. On the cellphone i use the nRF connect (a simple hyper terminal for bluetooth) and on PC i using the Advanced serial port terminal (a commum hyper terminal for windows).

Thanks for the help.

    Hi,

    There are a few different ways to share data over BLE. If streaming data is of interest, then GATT Notifications may be the best way to transmit the data. However, if you want to simply read values every once in a while, then you may store data in a BLE profile within the characteristics and read them with a BLE central. A good example project to start it would be the SimpleBLEPeripheral project included in the SDK. Here you can add characteristics to contain whatever data is of interest and read these characteristics with a phone app or with another BLE device running in the central role.

    I highly suggest reading through the CC2540 and CC2541 Bluetooth® Low Energy Software Developers Guide  as it contains very useful resources on developing with BLE. It also contains information on the GATT notification API.

    Best Regards,
