Problem nrf_esb with repeaters

[Joel V]

Hi,

I have opened a ticket with Kenneth and verified it by mistake. It is now locked. I have done the changes Kenneth asked me but it didn't resolve my problem.

thanks,

Joel

I assume this is a continuation from:
https://devzone.nordicsemi.com/f/nordic-q-a/86737/nrf52833-and-nrf52840-problem-with-nrf_esb-repeater

Are you able measure the current consumption when the repeater enter this state (e.g. using Nordic PPK2)? Just to get an indication whether they are in constant receive mode and/or continously switching between receive/transmit? Does the problem also occur with only one repeater?

I don't have the Nordic PPK2, what should be the current consumption in either of the 2 states ?

The problem also occur with only one repeater although it is less likely.

Thanks

The power consumption will depend on output power, ldo vs. dcdc mode, supply voltage etc. But if you for instance using the online power profiler for BLE you can put in your chip settings (if you are you using the nRF52833 then you can choose the closest which is the nRF52840). From the graph you can find peak current consumption in both tx, rx, and cpu (post-processing):
