Is there any difference between nRF52810 and nRF52811?

[tony55723]

Hello,

I used to use two nRF52810 for testing.

Using Timeslot (BLE+ESB), one of the 52810 paired mobile phones Bluetooth simultaneously sends the ESB.

Another 52810, as receiving ESB signal

The test was successful in the 52810, transplanted to 52811, only the BLE function is normal.

In nrf_esb_event_handler, always notify NRF_ESB_EVENT_TX_FAILED

Is there a difference in the chip? Because the 52810 is normal

Thanks

Hi

Can you let me know what the revision code printed on the chips you used for testing?

The nRF52810 and nRF52811 should work the same, but the current nrf_esb library is not tested for the nRF52811. 

Best regards

Hi,

Thank you for your reply

My problem has been solved temporarily, but I don’t know much about ESB.

It seems that there is not much difference between 52810 and 52811.

I keep another question, I want to know more about ESB.

Thank you so mush.

Hi

No, the nRF52810 and nRF52811 should be very similar, the main difference is the improved radio in the nRF52811 allowing for things such as direction finding in Bluetooth 5.1.

I am handling your other case, and just sent you a reply ;)

Best regards
