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...

Hello,
I'm currently porting all my C++ code from SD130 SDK10 to SD132 SDK12 and I also upgrading from device_manger to peer_manager.
I've noticed that in peer_manager_types...
Hello,
It seems that NRF_LOG_BACKEND_SERIAL_UART_BAUDRATE has wrong documentation. In sdk_config.h it says:

Dear Nordic Team,
Thanks for support.
I want to know the possible for nrf52832 act as a sniffer. If it is possible means i want to latest sniffer hex code.
Dear Nordic Team,
Thanks for support.
I have tested Current Time Profile sample application whenever connect with nRF connect APP the debug widows shows always "Current...
Good morning all,
We have a circuit based on 51822 chip.
We are currently trying to monitor some value from 0v to 24v from the analog inputs.
It's working, however...
I recently saw that SDK12.0 provides a Bootloader Cryptography module. I'm not certain after reading the documentation that this module can support my use case:

Hello everyone,
I am trying to implement a bootloader to my application to be able to enter in DFU mode.
I am using nrf51822 (32KB ram 256 flash) and s130.
I have taken...
My understanding is that the nRF51 is known to need a fairly stiff external pull-down resistor on SWCLK to avoid noise putting the chip into debug mode. I note that the nRF52...
