Hello,

is there a way to know the nRF51822 chip revision on the R Pro?

Thanks,

Alessandro

Eric

via the android/ios api or through firmware?

Through a custom firmware.

Is it also marked on the chip maybe?

@alessandromontanari All R series devices past and present are on nRF51 revision 2 silicon.  C series devices may have revision 2 or 3 depending on when they were ordered.  The nRF51 revision can be identified by the laser marking on the certified radio module: EYSFCNZXX devices are revision 2, and EYSGCNZXX devices are revision 3.  All devices are package code QFAA, which is QFN48, 256kB Flash, 16kB RAM.

The nRF SDK 8.1.0+ has a function to retrieve revision information: http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.0.0/group__nrf__ic__info.html
