About the demo running micro-esb concurrently with ble in Blogs

[OPQ]

Hi, I look at this demo,found that the ESB is PRX in most time, it may lead to a high power consumption.I want to achieve auto ack, piggybacking data in ACk from PRX.So the PTX is only work a short time,just when there are data need to be sended. How to achieve that?

Thanks

Hi,

To do that you can simply don't enable RX mode when the the timeslot starts on the PTX side. It's nrf_esb_start_rx() call inside TIMESLOT_BEGIN_IRQHandler().

Hi, Thanks. Yes,don't enable RX mode will not leadto a high power consumption,but in my application, I also want to achieve bi-direction data transfer between PTX and PRX,just like AUTO ACK.How to do that?

[OPQ]

Because in ESB mode,ack from PRX can carry payload,so I think my PTX maynot need to work in RX mode.

As I understand you have no problem keeping the PRX in RX mode all the time and power consumption is not the problem here.

On the PTX side, when you send a packet, with the NRF_ESB_DEFAULT_CONFIG configuration we have, auto ACK is enabled, esb library will switch to PRX mode automatically right after it transmit the TX packet. You don't have to do anything.

Hi, Yes,I can enable auto ACK,but in the PRX,I can't found anywhere to fill my ACK payload.
