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

Hi.
I'm using PCA10028, SDK10.0.0 S130.
I think "ble_app_hrs_rscs_relay" provides Central function and Peripheral function.
So it should be advertising right after running...
My program doesn't use SoftDevice.

Hi,
I've looked at the example codes provided by Martin in these two topics for communicating to a MPU6050 through TWI:

Using nRFgo Studio as the interface I try to download the file “set_in _test_mode.hex” and get the error above.
What are the proper steps to get DTM...
I am trying to reset and halt the target nRF51822 under SWD protocol.
Could someone point out the register to achieve the same? I looked up the reference manual but couldn...
Hi.
I'm using PCA10028, SDK10.0.0, S130 and "ble_app_uart" as reference.
As I've researching nRF51 with Central device,
it returns

Hi,
I'm using long write in one characteristic but if I try to configure this characteritic with write authorization (attr_md.wr_auth = 1) it doesn't work. I need to send...
My setup is as follows

1 RTCC
1 SPI Flash device
I want to set up the PPI to periodically sample the MEMS devices and the RTCC...
Hello,
I am trying to remove the use of the frame pointers for bootloader_util.c because I am getting the error : "r7 cannot be used in asm here", but I only know how to...
I use nRF51822( BLE nano) central mode to connect annother BLE nano (ibeacon mode), then I call disconnection to the peer address. Sometime, the disconnection callback will...
