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...

Hello,
I am trying to understand how to appropriately handle the Device Manager event of DM_EVT_SECURITY_SETUP_REFRESH as a peripheral.
This occurs when the user loses...
Hi, I wanted o increase the frequency at which heart rate is updated.
So I made the following change

Hey guys!
I am using your spi-master driver from the SDK 11 with the nRF52 chip. I am trying to read data from a MPU-9250 chip, and through my logic analysis, it seems...
Hi to all!
I've developed a board with NRF8001 on it and it works fine. But I've noticed a strange behavior. I use a mobile phone with NRF master control panel to work...
Dear All,
I am making IR transmitter using nrf51 where IR codes saved in SD card using PWM library we can transmitt the code while BLE is working.
Is it possible that...
Hi,
I am working on some application in which i have combined multiple profiles in one code.
In this i don't want generic access and generic attribute profiles to be displayed...
Hello.
I am using RTT successfully with nrf52 and IAR. But the start address for the RTT control block is a moving target: it changes whenever my code changes. I want to...
The product specifications publication for the nRF51822 doesn't list a gull wing chip pinouts found on the PCA10028 found on the evaluation board, kinda wondering if there...
Can someone confirm that all that needs to be changed to make code run with the SD installed is to change the linker to link to 0x1C000 instead of 0x00000 ?
To test, I...
I am playing with nrf51 DK. I used the following sample code,
