https://devzone.nordicsemi.com/f/nordic-q-a/9421/using-esb-with-s110-on-a-beacon-boardI intend to use ESB to transmit data every a few hours. Since I want to use a beacon board, I assume the ESB app needs to sit on the S110 softdevice. I added S110 to the ESB TX example code (esb_ptx_ack_payload_pca10028) in SDK 9.0.0.

The beacon kit ships however with preprogrammed S110 softdevice and a bootloader, but if you <a href="https://devzone.nordicsemi.com/question/20371/ble_app_beacon-and-nrf51822-ek/?answer=20857#post-id-20857">connect a programmer to the Beacon kit</a>, you can erase that softdevice and bootloader and flash whatever you want.</p> <p><a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk51.v9.0.0/esb_users_guide.html?cp=4_1_0_5_2">ESB</a> is a proprietary protocol and can not use BLE <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf51.v1.0.0/softdevices.html?cp=2_7">softdevice</a>.
