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...

Can nRF51 be BLE connected while it's on sleep mode? (connected by other device as Peripheral mode)
I thought, to be connected as peripheral mode, It must be advertising...
Dear Nordic Team,
We have a customer that would like us to extend an C# desktop application to use serial over BLE. What is the best dongle firmware and Windows driver...
Apologies in advance for what could be a rudimentary question. I have a large nRF52832-based project that only uses floating point in a few small but important places. Although...
Hi,
I would like to implement DFU with firmware encryption. I'm aware this isn't present in SDK 12 and would like to modify the secured bootloader to implement it.
As...
I'm seeing the sd_ble_evt_get return NRF_ERROR_DATA_SIZE even though the supplied buffer and length param are larger than the event length. Is this a known benign issue? ...
I need to upgrade my soft device from "s132_nrf52_2.0.1_softdevice" to "s132_nrf52_4.0.2_softdevice". As i am migrating from SDk11 to SDK13.
While migration i found out...
