What is bluetooth le multi advertising? -


i couldn't find clear explanation bluetooth le multi advertising.

for example, in specification of bluetooth system, see description of ble advertising not multi advertising.

what difference between ble advertising , multi advertising?

thanks

bluetooth smart has 2 ways of communicating. first 1 using advertisements, ble peripheral device broadcasts packets every device around it. receiving device can act on information or connect receive more information. second way communicate receive packets using connection, both peripheral , central send packets. focus on advertisement several reasons:

you can’t create connection between 2 devices without using advertisements. defining data , format of advertisement packets first thing work on when developing ble device. large number of ble products sleep of time, waking advertise , connect when needed. means advertisements have big impact on power consumption. users want responsive products, , advertising interval critical in quick connections. advertising design unidirectional. central device can’t send data peripheral device without connection. single peripheral can advertise multiple masters in area.
