Nordic nRF52840 - Multiple ADC channels sampling and transfer to BLE5 UART and write to FLASH - using FREERTOS


1. Sample multiple ADC channels with ability to change the sampling rate. (saadc)

2. The ADC Samples need to be written to FLASH and/or Send via BLE5/4.2

3. The Sampling start/stop will be done using button connected to GPIOs

4. Also some LED blinking

5. All should be based on "ble_app_hrs_freertos" example (Using FREERTOS)

The board is nRF52840-DK (PCA10056)

I'm searching a programmer that have specific knowledge in nordic BLE devices (NRF52840)

Skills: Microcontroller, C Programming, Embedded Software, Bluetooth Low Energy (BLE)
