Can nRF Connect BLE be configured to send data to a slave device?

[xvhongpeng]

Dear friends,

           The nRF Connect BLE app is connected with a local device acted as Master. The app supports the configuration of the local device's GATT attribute table, and adding attributes to the server setup allows the local device to exchange data with a connected slave device. However, after we configure the local device as a GATT server, how can we send data to a slave device via the local device after this configuration? Can the app make it? thank u.

Hello xvhongpeng,

 I am not sure I understand what you are asking here. Also I see you have a very similar thread, please stick to only one thread for the same question.

  Please use BLE terminology Central & Peripheral when you are trying to describe your setup.

As I read your question you are using your smartphone as peripheral, and you "configure the GATT server" and you use a nRF device as a client?

 

Anyway, I would suggest you to use "nRF Connect" on your PC that works as a client, then it is easier to see the different services and you can play around with the characteristics. 

(Also take a look at the BLE tutorials for additional information about BLE communication)
