the data transmission in the unconnected state

[Mark]

Hi,

My requirements are:

My essential need is a one-to-one connection between central and peripheral .

But when my central receives the specified command to start scanning, I want all the peripheral led lights with matching names to light up.

How can I do this? One is the data transmission in the unconnected state, and one is the nature of the one-to-one connection to actually control the leds of multiple peripheral to light up.

Thank you.

Hello,

Sorry. This is not something we can help you with.

You should find examples in the nRF Connect SDK that show usage of BLE (such as advertisement, scanning and connection). If you need a peripheral device to do something "special" such as turn on LED, then you will need to connect for a short period of time, write to a characteristic that turn on the LED, and then disconnect and scan for the next one.
