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...

The accelerometer values...
For a device that has APPROTECT enabled, it is required to use nrfjprog --recover to re-enable access.
What is the mechanism that nrfjprog uses to perform the --recover...
With the nRF52, is the RTT functional when APPROTECT is enabled?
I would expect not since the RTT relies on memory accesses which should be disabled with APPROTECT
Hi,
In SDK11, it was possible to call app_sched_execute() from a function that was itself called from the scheduler:
void app_sched_execute(void)
{
void * p_event_data;...
If you dont have an external 32Khz crystal for the nRF52832, besides the higher power consumption, are there any other issues ? e.g. CPU starvation affecting my app during...
Hi all,
I work with a nrf52, my project send and receive Beacon data.
when i work only with 2 card all works fine but when there are several transmitter and 1 receiver...
I've got an nRF52 application which is based on the nRF OpenMesh github.com/.../ but has been vastly customised. The application either acts as a mesh device and allows a...
As the title,I recently want to use nRF51822 to communicate with SmartCard in ISO7816 interface. but I don't know how to do this.Can anyone share the example code online ...
Hello,
I am using the nrf sniffer from adafruit to pick up ble packets from my NRF52. Everything has been working fine for the past 3-4 months. Yesterday I wanted to test...
