Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

Hi, I wrote a custom service with a characteristics with notifications support. After a client connects I start the sensors and I start updating the values. On the service...
On top of almost all the BLE examples in the SDK, there is an APP_TIMER_OP_QUEUE_SIZE define. How can I know how big this should be for a specific application?
Hi,
My project need to transmit mass data(maybe over 64kB)to APP once.But the total transmiting time is better not over 30Min.i use your example nRF51_SDK_8.1.0_b6ed55f\examples...
With the nRF51, it was not possible to run a high frequency realtime task due to the SoftDevice running with the highest interrupt priority, is this different for the nRF52...
