Multiple Peripheral to one central nrf connect sdk

[Ashishsult]

Hi,

I use the central_ht example and modified the prj.conf by adding

CONFIG_BT_MAX_CONN=8
CONFIG_BT_MAX_PAIRED=4
CONFIG_SDC_SLAVE_COUNT=2

And I expect atleast 2 peripheral to be connected and send data to the central.

But only one connects and send data. Moreover, when I add CONFIG_BT_LL_SW_SPLIT=y then both the peripherals are connected but then I get warning 

[00:03:15.721,771] <wrn> bt_conn: Found valid connection in connected state
Create connection failed (err -22)

Am I missing something?

Hello,

I would like to know if you have two peripheral devices or one device with multiple advertising. The last one will not work as bluetooth specification does not allow multiple connections to same identity. 

Thanks.

Hi Kazi,

Meanwhile I checked it more. I see that the code works sometimes but I need to reboot central multiple times so that it gets data from all the peripherals.

I was expecting that it also starts receiving data from other peripherals as well while busy receiving from others.

Here is the code for peripheral. I use the standard code from the given sample.

Hello Kazi,

There is no filter in the Central_ht (in my code), can you check it again please?
