Hi,
I want to read and write text data using a custom service. I have added the service and characteristics. But I could not read and I am not able to decode the data which I have written. Is there any sample programs for custom service? Please look into this and suggest your opinion.
You can use peripheral_server_uart and central_client_uart examples .
To verify the Bluetooth Low Energy functionality, use RSL10 or another third-party central device application to establish a connection. In addition to establishing a connection, this application can be used to read/write characteristics and receive notifications.
ble_custom.c - Support functions and message handlers pertaining to the Custom Service Server
GATT : Server ,
Write random values for instance 1 , 2, etc.
GATT : Client
On the receive site random values data entered via phone application will be visible in UART terminal.
Binary tab values : 0b0001 , 0b0010 etc.
GATT: Server
Type your data in UART terminal . In this case Hexadecimal format 0x6F to be sent to the connected Client RSL10.
GATT: Client
Data 0x6F can be read in the mobile phone application.
