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,

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

    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
