How to send string between Android device and CC2541 Keyfob ?

Hi wun,

1. You can start with SimpleBLEPeripheral project on CC254x.

2. You can use Android API to write characteristics. More info here: http://developer.android.com/guide/topics/connectivity/bluetooth-le.html

3. You will automatically receive the data on the CC254x if sent from the Android device.

I have try to connect to the CC2541 by KeyfobDemo project.

And I make the make the buzzer beep on CC2541 by using writeCharacteristic and IMMEDIATE_ALERT_UUID.

But I want to send the text string to CC2541 , but I don't know which UUID can send the string ?

And How to receive the string from Android device on CC2541 ? 

Hi,

The keyfob demo doesn't really provide a good UUID to use for strings(you would have to create your own). It is easier to use SimpleBLEPeripheral in this case(ex. use SIMPLEPROFILE_CHAR1_UUID)

The CC2541 would receive the bytes corresponding to ASCII characters.

 

Hi iam trying to send a asimple text from cc2541 to android using the simpleprofile_char_uuid but cannot find in the code where the acutal sending to android

Hi you can send notifications from the CC2541 to the phone. note you have to enable notifications by writing to the CCCD characteristics on the CC2541 from the phone. You can see char. 4 as an example.
