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,
Device should run clock without stopping.
So one of RTC should run.
And device will run NUS peripheral.
In such conditions, i know that i should not use sd_power_system_off...
Hi, I am trying to develop my own board with on board nrf24L01+ coupled with ATMEGA328p . I want to know if there is any schematic of the same in EAGLE or if you have the...
Hi, I try to read data from the ICM20948 IMU with I2C from my nRF 52840 DK.
Initialization of the device is correct, the IMU ID is sent to nRF correctly which means that...
Hi I am working on nRF52832 board.
i am using fds library to store my data. data contains MAC address. Each MAC address is stored in each record with same file ID and key...
Hi ,Sir:
We have a smart pen coming to market, but we have a problem with directed adv(based on SDK14.2 ble_app_hids_keyboard ). The problem is following:
when the pen...
