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
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
i made this project to try to create RSC service on arduino

unfortunately the server starts but i'm not able to...
Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
Hi,
My desire is to connect a BC832 module (with nRF52832 on it) to a UART on a controller board and then send data from an iOS app (programmed in Swift) through the BLE...
Hello,
I need two signals with a phase shift to control my motor. For some reason, completely randomly, sometimes my GPIOTE event is not triggered and i get the inversion...
Hi All,
Based on nRF52832 SDK14.2 rtc example, I want to change it to retrigger RTC Compare0, let the LED1 also toggle every 3s, instead of keeping LED1 on. I tried to add...
Hi, guys, I have an IR receiver module with 3 pin (AX-1838HS) ?
How can I use it on my nrf52832 ? I have PCA10040 development board. I don't know how to connect them and...
I need to drive a stepper motor without software intervention, since strict timing is a must.In the following image you can see the required wave-forms - the motor requires...
The SD API (S132-6.0.0) documentation provides little beyond what one could guess from the function and type names. sd_mutex_acquire says "Attempt to acquire a mutex". nrf_mutex_t...
Hi i am doing a prosject to get notification on cell phone when i get mail in my postbox (postbox outside the house) I am using a nRF51 dongle, and want it to connect to cellphone...
Hi! I'm working on HID mouse example on SDK 13.0.0. I'm supposed to use this as a low power media button control. I've done a few modicifations on the code for power optimizations...
I know that few companies choose to use NRF528001 with a separate microcontroller like Fitbit.
I would like to know why would they do so instead of using an NRF52 chip that...
Hey,
I am using a nRF8001 with a STM32L051 as an application controller.
After resetting the nRF the RDYN pin goes low, as expected. Then I'm setting the REQN line LOW...
Hello all,
I have a Nordic Thingy 52 board, and I have download the Thingy 52 SDK, I can debug it successfully.
But after I debug it , or download it, the board runs with...
We have an application with FreeRTOS. If we do not initialize softdevice, the freertos interrupts tend to come in at a very very slow rate. I know that softdevice does clock...
