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...

What is the proper way to setup notifications?
Right now, if I call ble...
Hi,
Warning: This might be a bit of a rant.
Is there going to be an effort made to make more of the nRF52 hardware drivers compatible with FreeRTOS?
Hopefully constructive...
Hello,
I am starting from ble_app_multilink_central example in SDK11.
Per the comment, when updating the number of central links, RAM setting should also be updated...
Hi,
