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
Firt I connect to Android device and keep one whitelist.pp_addrs and one whitelist...
I am testing the Nordic nrf51822 chip.
I have rewritten a bootloader example allowing firmware updates via Bluetooth LE (FOTA). A mobile phone will sent the update package...
Hi,
I'd like to transfer some data from my App (using fstorage) to the bootloader (using pstorage).
Given that that the two storage mechanisms are different, how can...
Hello, I've been working on porting a bit-banged control of a peripheral to use nRF51 SPI--which is just SPI rather than SPIM (therefore no DMA). Observe the SPICLK waveform...
Hi guys,
I am developing a project where I have a large group of NRF52 chips together in one room. In their normal state each chip is paired as a BLE peripheral device...
We are working on a NRF52 DK. In the data sheet of NRF52832, there is no mention of enhanced shock burst mode or dynamic payload or multiceiver. Do I need to refer additional...
we're using Mbed for NRF51822. our board using 2 GPIOs interrupt.
problem: the Rise edge did not generate the Interrupt event: set EVENTS_PORT.
I try uisng while, but...
Hello,
I will explain my setup:
I have 2 nRF51-DK each one of them connected via I2C and SPI to two different custom boards. One being the central(nrfA) and the other...
Setup: DK #1 is running native S110/SDK10/nRF51, one service 128-bit w/ 16-bit char:
Service UUID: 0x0xb1ad
Service UUID type: 0x0x2
Service handle: 0x0x0c

Hi,
I tried to familiarise with eclipse environment and i have some problems :
The debug and run button. I searched on google but i didnt found anwser.
How can i define...
I find example : nRF51_SDK_7.0.0_2ab6a52\examples\properitary_rf\esb\esb_ptx_prx .
question 1: can i add this example into my project that build on SDK v610 and it run...
Hello,
I have an problem with DFU on nRF 52 I have followed this thread devzone.nordicsemi.com/.../ but failing to upload firmware.
I have attached screen shot. You...
Hi
I have noticed that the moment I start SAADC task ("nrf_saadc_task_trigger(NRF_SAADC_TASK_START);"), my CPU current consumption rises by 2 mA!
