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

I have troubles with connection using nrf51822 and android phones:
First I connect and bond the device to the phone and it works ok.
Then I periodically...
Hiya,
Regarding voltage amplitude peak to peak for external high-swing clock HFXO 32MHz, what's supply rails？I don't find out this specification defined in datasheet PS_V1...
My phone is like beacon that transmit service data.
(I checked service data in different phone.)

Hello,
I am really new to the field, I apologise, if things I am saying do not make sense, explanations and corrections appreciated :) I am trying to reach IPv4 internet...
Hello,
I would like to make use of an external ADC that is connected to my nRF52832 through SPI & easyDMA,minimizing the use of the CPU (or without using the CPU).
The...
Hi all,
I am started my project using the softdevice S130 v2.0.1 and the ble_app_uart example(SDK11) on a custom board with the nRF51822. I had to made some changes for...
Hi,
after porting an existing application from version 3.0 of the s132 SD to version 5.0, I experience, that sd_ble_gatts_rw_authorize_reply() returns NRF_ERROR_INVALID_PARAM...
I want to use the SPI in master mode, but the slave just have three lines,the miso and the mosi is the same line,but I don't know how to config the pins? Do the nRF52832 supports...
I WANT COMMUNICATION BETWEEN A NRF51422 AND NRF528321 BOARDS, IN WHICH IN NRF51422 BOARD I WILL MEASURE PWM COUNT(IT IS PHERIPHERAL) AND SEND IT TO NRF528321 BOARD WHICH IS...
I am trying to wrap BLE into a nice c++ class.
For this i am using ble_app_uart example.
I think it was working fine until i was up to clean the helper functions.
After...
Hello,
I have a nRF52 as central and a cc2650 as peripheral, when I received advertising answer, I can't see the full size of advertising data (see 7 instead of 31). With...
