Yes, use a app_timer (see this guide) and call ble_nus_data_send() in the timeout handler.

Hi Sigurd,

Now I am using ble_app_uart_c and ble_app_uart but I couldn't send the data byte without pressing anything from keyboard. Is it possible to achieve the nordic sending some data byte within some period of time without pressing any thing?

Thanks!

Hi,

I used ble_app_uart_c and ble_app_uart where I need to type some command so that my packet data will send to central. Is there any way that I can advertise my packet load without typing anything from the command prompt within some period of time.besides, I have to send 8 peripheral data to a central where I tried with 2 peripherals but I always need to reset to change to another peripheral.

There is a original simple API "ble_advdata_set" which is easier to use. If I want to have the same function of this API what should I do?

Hi,

The LED characteristic used in ble_app_blinky example is configured to have a fixed length of 1. If you need characteristics that are configured for max payload, I suggest taking a look at the ble_app_uart example instead.
