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 use BLE mesh github.com/.../nRF51-ble-bcast-mesh
but when I use the master control to write values to update the values of services, the following error occurs: "global...
Hi,
I have implemented the support for 'long write' as in
github.com/.../ble_app_hrs---LongWrite
which works from the MCP... except that on BLE_GATTS_EVT_WRITE, it seems...
I have bought nrf go starter kit with pca10005 board( nrf51822 ic). I want to program the nrf51822 using these tools.The guide that I got from the nordic website not explaining...
If the device is paired (but not bonded) using "Just Works", sd_softdevice_disable() causes the application to hang/crash (nothing happens until reset by watchdog timer)....
I want to generate 2 fast PWM waves with 25% duty cycles from nRF51822. They have same frequency of 4MHz but there is half a cycle delay between them. I checked the nrf_pwm...
Hi,
I am trying to get the NRF8001 rev. C chip working with a Tiva Lauchpad (TM4C123GXL) board. I modified the original Arduino SDK for use with Energia. I am using the...
Hello,
i want to write a global unsigned long variable in RAM after programming the device. The Use-Case is to set the clock value to the actual time. So the new unsigned...

Hi. All.
I am in the process of update SDK 9.0 from 5.2.
Meanwhile, SPI couldn't read from external flash's data.
Unusually SPI works well before infinite loop, I tested...
Hi there is a problem in github.com/.../nrf51-UART-examples
any one can help?
I put empty loop in main, and comment off all ble related int. and I process uart_evt by...
I want to use the nRF51-DK board as a programmer for my target. As I understand it, this can be done with the signals on P19. However, there is one signal, EXT_RESET, that...

Hi,
I would like to ask if someone has experience using the AES. I n eed to be absolutely sure that the user SW can use the AES HW block for own custom usage. If yes, Are...
I'm using SDK's interface for AES ECB block, but getting a hard fault when ECBDATAPTR is redirected at ecb_data in the initialisation function:
