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...

Starting with the dev kit, where I get correct behavior. First, I make sure the RESETREAS register is all zeros. I do this like so: NRF_POWER->RESETREAS = 0xFFFFFFFF; while...
Hello,
I am using nrf9160 and want to test the just simple SPI function. The code that I found from github( https://github.com/Rallare/fw-nrfconnect-nrf/tree/nrf9160_samples...
Is there a way to set duty cycle before app_pwm_enable(&PWM1) call ?
Or some other simple way to switch on and off a passive buzzer signal without every time at off/on cycle...
Hi:
We're working with a 3rd party testing agency for our product that is using SDK 11 with S132 Softdevice 2.0.0.
If I understand correctly, the SDK allows up to 6 transmit...
I am trying to implement a system / integration test of a BLE device.
I would like to use the nRF52840-Dongle in my PC and use the PC-BLE-Driver for Cpp as the Central....
As you could see from the below image, the SCL signal at 400kHz is NOT a good square wave.
1) Why & how to solve it, please?
2) Also, why SCL is between 0.4V to V_DD=3...
I am now pulling my hair out with these drivers ... I'm trying to do what I think is the right thing and use the new nrfx drivers, but it's really not easy.
So this started...
Hi, I am using Zephyr's BLE for transmission In the peripheral, I record the time when I send the notify to cental (start time) Then when I received the central write_without_response...
Hello,
I have a peripheral that is connected to nRF52832 using I2C, in which I want to send some file to its memory. However, for sending this file, I need to stream it...
I have an existing BLE project that works as a mesh but does not use nRF SDK for Mesh. Using sdk 17.0.2, s140 7.2.0 on nrf52840s and visualGDB.
It works well for most clients...
Hi, I want to evaluate my anttena design. I have tuned it. With the dongle I can scan the air for radio signals, I see then my Wifi and I see the BLE radio of my board. Now...
Hello Nordic Community,
In order to measure battery voltage, I am using ADC with the code implemented as below:
In this, there is a while loop used to wait for ADC to...
