Can nRF Connect be configured to send data to a peer device?

[xvhongpeng]

Deer friends,

       The nRF Connect BLE app supports the configuration of the local device's GATT attribute table, also known as server setup. Adding attributes to the server setup allows the local device to exchange data with a connected peer device. We can configure the local device as a GATT server, but how can i send data to a peer device via the local device after this configuration? Can the app make it? thank u.

Hello,

Please check out one of our examples from the SDK, such as the SDK\examples\ble_peripheral\ble_app_uart.

 

It has the option to enable "Notifications", which is a keyword for your project. If notifications is enabled in this example, then the phone will get a notification whenever the peripheral/connected peer updates the value in this characteristic.

 

Please see this guide.

 

Best regards,

Edvin
