we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...
I am try this at nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard

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...
nRFgo Studio displays a "Enable reset pin" option on the nRF52 DK but does not display this option on our custom hardware; we use a Segger J-Link for programming the custom...
Hello,
I would like to know the CALIBRATEOFFSET function in detail.
Could you disclose the part of source code on this CALIBRATEOFFSET function?
Best regards,

Hi,
In production line, I was supposed to do BLE test using DTM with UART interface and MT8852B from Anritsu.
However, the antenna is specifically tuned for plastic...
