Is there any differences between NRF52832 and NRF52810 with ESB transmission?

[?????]

In my plan, I have used NRF52832  IC as the transmitter and the NRF24LU1P+ as the receiver. I have tested  the wireless transmission successfully.In order to reduce consts,I need to use NRF52810 instead of NRF52832. All the code of  esb configurations is the same,but I find  the Wireless transmission failure.

Hi Sanbao

The ESB libraries don't officially support the nRF52810 yet, but I would expect them to work since the radio in the two devices are more or less the same, and hte nRF52810 is designed to be software compatible with the nRF52832. 

What kind of hardware are you running the nRF52810 on?

Is this your own custom design, or a standard nRF52 DK?

Best regards
Torbjørn

Thanks for your help! This is my own cumston design.Will the ESB libraries support the NRF52810 in the furture?

Hi 

We are planning to add official support for the nRF52810 pretty soon, yes. 

I just tested the ESB examples in the SDK, and they worked fine both on the nRF52810 and the nRF52832. I only had to change the RAM size, to accommodate the smaller RAM in the nRF52810. 

Have you tested your board with any other examples, to make sure it works properly?

Can you run simpler examples, like the blinky example?

If only the radio is non functional it could be an issue with the high frequency clock. 

Best regards
Torbjørn
