Hi,
I would like to use the ble_app_hrs to send pressure values via the heart_rate_measurement_send function.
Unfortunately, they are too long: around 105000 Pa (equals...
Hi everyone!
I have an application based on experimental_ble_app_eddystone for nRF52 (SDK12.2), which uses FDS to save in flash memory. Now I want to add the secure_bootloader...
