I am getting get BLE_EVT_USER_MEM_REQUEST and BLE_GAP_EVT_CONN_PARAM_UPDATE event, when writing to ble device, sample code did not handle these event, and seems no document...
Hello:
Why do I erase SDK5.2 version of flash and read not, in SDK4.2 can. I tested nrf51_sdk_v5_2_0_39364\nrf51822\Board\nrf6310\flashwrite_example is a good example.However...
before i write the flash, it has been erased.so ,its value is all 0xff.
when i write 0x00 to flash address 0x0001,the value read out is not 0x00 but 0x01,and the value in...

I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hello again,
i wanna use the UART communication for transfering data from my µc to the nrf51 and vice versa.
For a test i used the ble_app_uart example and it works...
Hi,
I programmed my NRF51 to read ADC samples and I trying to transmit the information to a dongle. So far I have been able to send the hexadecimal values of the recorded...
Heyho!
Is it possible to set the PWM base clock frequency to 40kHz? If so, how? I see that the predefined base clock frequencies don't go any lower than 125kHz.
I'm...
Hello everyone, I am program for PCA10001 and I want to use Bootloader to upgrade firmware through OTA for my device. I have a old file bootloader use for s110, and I tried...
Hey,
I would like to send data from Central to Peripheral. I follow by ble_app_uart example, however I need to send a float type variable, so I split it to the total and...
I have 2 identical nrf52832 development boards with PCA10040 V1.1.0. One is running the ble_ant_app_hrm example from the nRF5_SDK_11.0.0_89a8197. This example appears to run...

Hello,
I am trying to remake an nrf52 project in Keil and ran into a problem regarding stdint.h. There is already an "include <stdint.h>" statement and Keil has not reported...
Hi,
I am testing the NUS using the UART example in the SDK11 with the PCA10040 board.
Since I want to achieve the maximum speed of transmission I used the FIFO buffer...
I am having issues waking up nRF52 with s132 using the RTC interrupt. The same code is used on nRF51 with s130 and does not show this behavior.
The RTC is configured and...
Hi,
is it possible to have the same configuration as in the example ble_central_and_peripheral but with ant+ as peripheral (on nRF52)?
Thank you for your attention
I am doing externally triggered SPIM transfer on the Nrf52 using PPI.
I found that the NRF_SPIM_TASK_SUSPEND is a very power hungry operation as SPI suspend waits for the...
