I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
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...
Hello all,
I'm practicing creating my own service following instruction from this link: https://github.com/bjornspockeli/custom_ble_service_example
Now I stuck at part...
Hi everyone,
I have configured two UARTES , one using the app_uart library and another using nrf_serial library.
I am using SDK15.0 alongwith s140 softdevice with bluetooth...
Hi There,
What are the difference between system off, ram retention, RTC wakeup vs system on with ram retention, RTC wakeup vs FreeRTOS tickless with RTC wakeup? And what...
Hi team,
I noticed a very interesting incorrect pin description in the latest product specification of v1.2 for nRF52810, QFN32.
Above picture shows we have 2 p0...
I'm using the PCA10056 with an SD card connected via P1.12-P1.15. When I use the FatFs example of SDK12 PCA10028 it works fine. but when I use the FatFs example of SDK15.0...
Hello,
I've got the nrF52840 and would like to create a simple application to send temperature to my laptop. Then the next step would be to create some mesh network with...
Hello,
I am working on Custom BLE HID Keyboard. I am currently trying to understand working of program given by nordic in SDK-10.0.0. THere is one problem which I am facing...
Hi,
I've tried to implement the DFU_buttonless example to my development board. I programmed the bootloader and the settings-page. The bootloader detects the application...
I'm currently in the prototyping phase of getting two nDK52840 boards talking to each other. I currently have one board flashed with the central role, and another board flashed...
Hello.
What do I need to run this example called uart?
As far as I understand this should be simple echo program meaning what comes in goes out but I can not see anything...
I want to use nRF52-DK for receiving data over UART and send it over BLE link so I loaded the ble_app_uart but hard fault occurs immediately in these circumstances - 1. If...
UART works fine as long it is configured on port 0:
But if it is configured to port 1, it does not work:
and compiler reports a warning in serial_uart.c, serial_uart_init...
I would like to test how our solutions react to a ble jammer.
is there any sample for the pca10040 dk to generate suchjam noise ? Or maybe you could guide me on how i can...
I thought I would be able to do the following, but when FDS_ERR_NO_SPACE_IN_QUEUES occurs m_fds_no_space_in_queue never becomes false. Is there any way I can wait for space...
