https://devzone.nordicsemi.com/f/nordic-q-a/13446/esb-with-timeslot-throughput-issueHello Nordic People, I am working on making concurrent operation of ESB and BLE to set up sensor network. Currently, the initial set up has been implemented in such that: first device one samples data (internal ADC) and sends the data to second deviceen-USTelligent Community 13Mon, 25 Apr 2016 09:40:27 GMThttps://devzone.nordicsemi.com/thread/51324?ContentTypeID=1Mon, 25 Apr 2016 09:40:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8ef24265-08c4-4baa-90b7-41466b6e41df&#216;yvind Karlsen<p>Hi,</p> <p>When you do not use ACK you will have packet loss. With your timeslots you need to make sure that you are actually receiving on the multiprotocol device at the time you are sending from the ESB device.</p> <p>You are correct that the timeslot API allows you to utilize the same radio resource, it is a type of time division multiple access.</p> <p>In order to get the throughput and delay that you want you need to be able to synchronize the timeslot window with the transmission from the ESB. You could start to look into requesting windows at the interval you know that you will be transmitting ESB packets with.</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>
