Hi,

Like mentioned by Turbo J above, can you define what you mean by compatible? Give more details about what you are trying to do?

Are you trying to use the nRF52840 device with our nRF Connect app to find your nRF51822 device?

Thanks for your reply.

There is  one bluetooth module based on  Nordic nRF51822 SoC solution in our product.

Now,I wanna use nRF52840-Dongle to find the product on the scan list, but failed.

In this case, I wanna know if the nRF51822  is compatible with the nRF52840

I have a setup here that uses an NRF52840 module to talk to several nrf51822 (technically NRF51422 but those only differ in the ANT+ license) devices via bluetooth. So yes, that works.

Note that there is a bug that prevents the scan module from the SDK working with a UUID of 0x0000 - search this forum "flic button". You have to process the scan event in your own code if that happens to be your UUID or the UUID part of a custom GUID.
