[Junxian liu]

Hi ,I have one module designed based on Nordic nRF51822 SoC solution.But now ,I wanna use nRF52840 to make communication.I can't find the module with nRF connect app.  Does the nRF52840 Compatible with nRF51822?

Define: "Compatible". No, you cannot use the same binary from NRF51xxx on a NRF52xxx chip - you have to re-compile the software at least.

Thanks for your reply. You mean that I need modify the FW for NRF52 or use the NRF51  to make the communication
