I'm testing the nRF connect SDK 1.4.2 HID keyboard example (nrf/samples/bluetooth/peripheral_hids_keyboard) on an nrf52dk_nrf52832 and it doesn't seem to work. I have it open in SES, builds and runs ok. The only modification I made was adding configuration to prj.conf to enable RTT so I can see the debug output in SES:
CONFIG_USE_SEGGER_RTT=y CONFIG_RTT_CONSOLE=y CONFIG_UART_CONSOLE=n
It pairs correctly to both iOS and macOS. Pressing button 1 doesn't type a character though. Looking at the packet logger on Mac, it doesn't receive a packet, and in fact after pressing button 1 a couple times battery notifications aren't received any more. I haven't tried debugging any further as I haven't modified the project.
