multilink example in nrf52810

Hi,

is it any possibilities to multilink central with s112 in nrf52810 chip?

using sdk: sdk14

actually, i am using sdk14 with one central and one peripheral is fine, is any possibilities with s112 one central at a time connected two peripherals?

otherwise is any possibilities multilink with s112(nrf52810)?

Thanks,

    Hi Naren

    The BT832AF modules use the nRF52832 I assume, not the nRF52810?

    I am not quite sure I understand the question. Do you want to connect to one central device and two peripheral devices from your BT832AF module?

    With the S132 SoftDevice this is possible, but it would be nice to get a confirmation on exactly what you are trying to do.

    Yes,I am trying to connect one central device connecting to  two perphirals at a time.

    Bt832AF modules support nrf52810 only,

    Hi Naren

    Thanks for the clarification. 

    The nRF52810 should be able to do this, but you will have very limited memory left over for application code. 

    I tried to build the ble_app_multilink_central example in the nRF5 SDK with only 2 central links enabled, and it ends up using 182kB of flash and 23.4kB of RAM, which is very close to the limit of what you have available on the nRF52810.

  • Hi Torbjørn ,

    Thanks for reply,

    I am setting to NRF_SDH_BLE_CENTRAL_LINK_COUNT=1 ,it is working fine for ( 1 central and 1 peripheral )connection is fine(data also sending),but i am changed to NRF_SDH_BLE_CENTRAL_LINK_COUNT=2 for (1 central and 1 peripheral) it gets fatal error like these

    0> <info> app: scan_start
    0> <info> app: Connecting to target C2:DF:94:57:17:D1
    0> <info> app: p_ble_evt->evt.gap_evt.conn_handle : 0
    0> <info> app: scan_start ret:0
    0>
    0> <info> app: scan_start
    0> <info> app: Discovery complete.
    0> <info> app: Connected to device with Nordic UART Service.
    0> <info> app: Active Connection = 1
    0> <info> app: scan_start ret:8
    0>
    0> <info> app: scan_start
    0> <error> app: Fatal error
    0>

    Here error gets  NRF_ERROR_INVALID_STATE whenever NRF_SDH_BLE_CENTRAL_LINK_COUNT incremented.

    I am also sent sdk_config.h also in previous post.

    Thanks & Regards,

    Hi Naren

    You are saying that connecting to exactly the same 1 central and 1 peripheral doesn't work when you increase the central link count to 2?

    Did you make sure to also increase the total link configuration?

    Best regards
