Hi, detailed post which is much appreciated. Would you be able to provide me with feedback whether or not my system can use the aforementioned procedure?

My system will have 2x nRF52810 modules, one serving as a master and the other as a slave.

The master is an RTC module, which the time data will be offloaded from a mobile application. Once the set time is reached an interrupt occurs, and the appropraite events of the master shall occur. However, in addition when the interrupt occurs I want the master to communicate with the slave over BLE to send some commands.
The slave in

The slave is basically a multi-switch controller and the different commands shall switch on different devices.

The system was not done over one module due to the constraints that the devices operated by the master and the slave are not close to each other.

So my main question is, can I use the method you descirbed in this post to communicate with the master over mobile, and then have the communication seperate between the master and slave but obviously time multiplexed such as not to have interference and collisions.

Cheers and thank you.

Hi, nice post. You can also change advertisement payload on radio notification so you can be sure that every other advertisement the payload is changed. For example i had 300ms advertisement interval and 3 packets so approximately every second all three payloads were advertised. I also use "payload type" byte which can be 0x01, 0x02, 0x03 so android can know which one is currently in the advertisement.
