Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
i made this project to try to create RSC service on arduino
developer.bluetooth.org/.../runningspeedandcadence.zip
unfortunately the server starts but i'm not able to...
I'm looking at table 23.15.2 in the nRF5 Reference Manual, and it states that TX startup current is 4mA with the DC-DC enabled.
Does that 4mA include the CPU idling...
My project: nRF51422, S110, based on SDK 7.1.
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...
