What the difference between nRF51822 and nRF51422？

[Jason]

Hi， Can the examples in <keil_location>ARM\Pack\NordicSemiconductor\nRF_Examples\9.0.0 of PCA10028(nRF51422 chips) be use on nRF51822 chips? Or how to modify it to adapt a nRF51822 chip?Thanks.

The 51422 series supports the ANT protocol. The 51822 does not. Both support Bluetooth LE and Nordic's Gazell. I think most of the non-ANT 51422 examples should work fine on the 51822.

Yes, I have found that non-ANT stuff works equally on 51422 and 51822
