How to send a packet of bytes through connection peripheral mode ?

[Bluesky]

Hi, 

I would like to send multiple peripherals with each packet of bytes(244) to a central. I am using the blinky example from \nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\ble_app_blinky where I can only send a byte each time. Does anyone encounter or solved this issue ?

Thank you,

SKY

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.

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!

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