How esb PTX send multiple times when ACK is disable

[Dave_N]

I want to boardcast data using ESB to several PRX, how PTX can send multiple time let say 10 times under ACK is disable

Could you just wait for NRF_ESB_EVENT_TX_SUCCESS event on each packet and send the packet again 9 times more ?

If yes, how PRX side can distinguish whether this is new one or repeat payload, thanks Hung for your idea in advance
