Multirole Connection: can we send a broadcast ini advertising mode while in ble connection mode at the same time?

Hi,

I have 3 Devices that constantly broadcast their position to each other so the other can adjust the position each other. they act like master and slave but ther are no connection between them.

now i want to connect one of those 3 to a smartphone using connection mode but the problem is the smartphone can't detect the device which is now act as broadcaster in advertsing mode. is it possible to use advertising mode and connection mode at the same time?

how can i establish a connection between the device and phone while the device send message as broadcaster to another 2 devices?

is multirole still the most suitable solution to this problem?
