You can find the same example in SDK v6.1 in \Board\nrf6310\esb , I don&#39;t think there is much difference.</p> <p>But if you want to use with BLE, it is more complicated. If you want to use BLE and ESB not at the same time, then it&#39;s fine, you just have to disable BLE before you use ESB and vise versa. If you want to use them at the same time, you would need to use timeslot because BLE will block access to radio when it&#39;s active.</p> <p>We have an example of using timeslot for concurrent ESB and BLE <a href="https://github.com/NordicSemiconductor/nrf51-ble-micro-esb-uart">here</a>.</p> <p>2-. Yes you can combine, but one device can&#39;t be PTX and PRX at the same time, they can take turn.</p><div style="clear:both;"></div>
