Regarding nrf52832 central with multiple connections

[chetanhiremath]

Hi Technical team,

I want to use nrf52832 for my project, below are the some doubts i have with nrf52832

1) nrf52832 will act as HUB and receive data from peripheral devices every second, there might be some 7-8 peripherals(nodes) sending data to central(nrf52832) every second.

a) Will nrf52832 in central mode able to make those many connections at a time?

b) Will nrf52832 be able to collect data from multiple nodes at a same time?,if yes the how can i achieve that?

Please help me out on above doubts.

Regards,

Chetan

a) Yes. The nRF52832 is capable of being connected to up to 20 devices simultaneously - so the answer is yes.
b) Yes. The data transfers will not occur in parallel (since the nRF52832 only has one radio), but it will schedule the links so that the data flow from the peripheral devices appear to be happening in parallel although they are in reality time-slotted. 

Note that reading the data from the peripheral devices can either be done by pulling data from them (IE requesting new data) or receiving push-style message (IE the peripherals send data whenever it is ready without waiting for the central to ask for it.)

Hi,

a and b) The nRF52832 with the S132 SoftDevice support multiple concurrent connections, so this should not be a problem with such a long connection interval (on second).
