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'm using the nrf51822. and then I tested the samples to receive the ANCS and send to iPhone information of temperature sensor.
I would like to merge the two above-mentioned...
According to the nRF51 series reference manual.
10.1.2 Debug interface mode
Debug interface mode is initiated by clocking one clock cycle on SWDCLK with SWDIO=1. Due...
I have the nRF51822 Evaluation kit and put the Heart Rate Demo on the PCA10001 (V2.1.0). When I press Button 0 it doesn't advertise. I have the module (PCA10000) scanning...
Hi,
I was looking at the .map for my project and I noticed that pstorage.c was taking up a bunch of RAM (~600 bytes), which I thought was a lot, so I went into pstrorage_platform...
The document nRF51422_Evaluation_Kit_User_Guide_v2.0.pdf says:
Locate the Heart Rate demo project found in the folder

I copy static void radio_disable(void) and void radio_tx_carrier(uint8_t txpower, uint8_t mode, uint8_t channel) into my project.
I call radio_tx_carrier(RADIO_TXPOWER_TXPOWER_0dBm...
Hi all,
I have a spurious crash in the softdevice I guess.
It occurs sometimes when the master (an HTC-M8 android phone)
rapidly submits characteristic changes

Question:
If use "twi_master_init()" with "twi_hw_master.c", the current consumption is added 1m

Hi I am completely new to ARM development world. I have been developing for years for PC.
Now I am working on a Project where we have decided to evaluate nRF51822 chip...
I would like to know if it is possible to use the internal RC oscillator without calibrating every 4s with the softdevice disable. I just want to read a sensor every 2s and...
I'm interested in using BT LE to collect data from a number of serial based devices -- a point-to-multipoint configuration. I'm familiar with the UART examples and have seen...
Hi,
i am searching for infos about my concrete BLE-Sig certification situation but i cannot see the forest because of all the trees :o)
i am currently developing a BLE...
Hi,
I know that a lot of question exists on that subject, but I can't manage to have an accurate battery measure on [Nordic Beacon device] (battery CR1632 3V) ( www.nordicsemi...
Using the nRF Beacons app, but cannot see the battery condition of each beacon. Is this already implemented - if so how to turn on? If not how is it implemented?
