can an nrf52 series SOC transmite a ble message to 150 units in one second ?

[ziv123]

Hello

we are thinking of using the nrf52832 (sdk 16.0, s132) , which we are a bit familiar with by now.

We have a project in which we need to transmit data to 150 unit via BLE, we do not think of pairing with the receiveing units.

we are thinking of grouping the data for 50 units in one 255 byte message (so 3 messages and we wish to be sending serveral times in a second for each group)

if i want to send a 255 byte message via ble, how much time does it take ? how many messages like that i can transfer in one second ?

is it preferable to use bluetooth 5.0 if i have no power supply issues ?

if bluetooth is preferable then why?

and is there an sdk example or certain softdevice that support bluetooth insted of ble  ?

Best regards

Ziv

If you're broadcasting, as a beacon, then you have no idea how many devices are listening - it is essentially unlimited.

EDIT

AHA: it is a duplicate - not just the forum losing replies:

this is not what i asked... i know when you send a beacon everybody in the area can scan for it but i want to send different messages to different units, which i design as well, i don't want to create the pear to pear connection because i asume that will take to much time, each unit will read its own id in the message 

but the main unit needs to be sending 150 different messages in one seconds that was my question

regarding the dupilcate.. i send the same question one for hardware and one for software i thought it goes to different supporter engineers from nordic

So that's not "broadcasting", then - is it?
