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 done read and write operations on fds with dummy buffer. now when im writing new data into fds it is showing the previous data .can anyone give the function to erase...
I am trying to build a solution based on the nrf_ble_uart_c example. Building has been working fine until I added pin configuration statements.
I've tried relocating the...
I am incorporating the "pin_change_int" code to generate GPIOTE interrupts from an external device. I made a couple changes including renaming the function from gpio_init...
Hello,
I've been playing around with with the nRFsniffer for a couple weeks now. Adafruit was out of stock of the BlueFruit LE Sniffer so I ordered a BLE400 and a few Core51822...
I would like to program the NRF52810 with the SoftDevice 132 and my bluetooth program. Is there any way to reprogram the NRF52810 over bluetooth rather than using a wired...
Hi,
I'm wonder is the speed of i2c on nrf52832 can be faster then 400kbps? even use EasyDMA, the speed still can't faster then 400kbps? I also look into the max speed of...
Hello All,
I am a bit confused with the maximum speed that is achievable with the USBD CDC ACM driver.

Hi,
I have read all around DevZone that more details about AoA/AoD based direction-finding feature were expected to be released around Q4 of this year. This is very exciting...
Hi,
I am using nRF51822, and try to use the ECB block AES128 to do some data decryption.
From the SDK I found 2 API functions:

Hello,
I have tested and verified the code for my application on the NRF52 DK, but now I need to program my own custom device using the nRF52832 chip. I saw there was a...
