Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...

My project employs several application timers (run via the scheduler) and a continuously running Timer1-based 1ms timestamp...
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'm developing a product using nRF51822 which is intended to work with iPhones (only iPhones for now; iPod/iPad and Android later).
I need some kind of document...
Hello,
I'm trying to recreate the PWM_library example from the v.11 SDK in a new file in Keil. I have compared the debug settings in my project to the debug settings to...
Hi there,
I am following the thread to use JlinkExe and JlinkRTTClient. I encountered a situation which i don't understand.
After running JlinkExe (go to the folder...
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
