Connect via phone to nrf52840 that is already transfering data to another nrf52840 ?

[embo san]

HI, I have actually couple of (connected) questions,

1. Can a phone (v4.2 bluetooth) connect to a nrf52840 board that uses 5v bluetooth?

2. How many (BLE) connections (simultaneously) can nrf52840 board handle?

3. If I have two nrf52840 boards talking to each other via BLE (sending/receiving data) does the (already) connected phone keep connection to the board, or the connection is lost

when speaking of connections, I'm always talking about Bluetooth and BLE

thank you

Hi Embo,

1. Yes, v5 is backward compatible with v4

2. nRF52840 running S132 support up to 8 connection as a central, and 1 connection (for now) as a peripheral. Usually we use the phone as central, then the nRF52840 can only connect to one central at a time unless you setup the phone as a peripheral and nRF52 as central. See S132 Product Spec at section 16.1 .

3. Yes, it's possible. It's described at 2. It's either the phone have to be peripheral and connect to a common nRF52840 central or one of the nRF52840 have to be peripheral and central at the same time.
