multilink central S120 transmission

[wiki]

Hi NORDIC

I neen to implement a function that multilink central (S120) can receive information from multilink peripheral . I do not know how to implement it in software.It is importent for me to complete this task . I hope you tell me or provide something that will be usefull to me .

Hi wiki,

Could you tell me more information on the set-up. Do you plan to have several central to connect to one or more peripheral at the same time ?

If you want several central device share the same peripheral, it's not possible with BLE.

BLE only supports one central to be connected to a peripheral at a time. You can have several peripheral connect to one central, but not the other way around. It's a star network.

You can of course implement your own proprietary protocol and use timeslot API to control the radio in between BLE event. But it's upto you to implement and it might not be equivalent with BLE spec.

Hi wiki,

I don't see any difference between transfering your data and sending command to turn off and on the LED. We uses 1 byte to send the command to control the LED, you can modify it to send anything within that 1 byte. If you want more than 1 byte, you can change the length to upto 512.

You mentioned "they can not match", what exactly happened ? Besure to use ble_app_hrs_c for the S120 application. and ble_app_hrs for S110 application
