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...
Hi,
I'm trying to flash the firmware to some custom built pcb's with NRF52840 on it. The first time I flash it, it works great.
Then, if I try to erase the chip (or any...
Hello
I have this firmware running in C:\Users\danie\ncs\v1.5.1\nrf\applications\tracker on the nRF9160-DK, nRF9160 SICA B1 is the marking on the chip
Modem FW is...
Hi. Some questions regarding the nRF9160 ENABLE pin:
1. According to the nRF9160 product specification the ENABLE pin voltage requirements are like this:
In the first...
Is it possible to add additional UI for different sensors in nrfcloud platform ? I could see that there is a predefined list of sensor types that can be attached to cloud...
Hi,
I am using two nrf52840 boards and a Light-Switch example included in the mesh SDK_v5.0. I would like to measure the time required to send a message from client to server...
Hi all,
I'm working on this example: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v3.2.0%2Fthread_example_dfu.html
I'm struggling on the server part, I...
Hello,
we are developing a verry small sensor node. Since we like to know if the sensor we are connected to, is one of our sensors instead of an attacker fake sensor we...
Hi! I was testing GPIOTE with pin_change_int example and tried to add a log to the push of the button.Somehow the code is not working, it is indeed changing the state of the...
nrf52840, sdk17. pca10056 (for now). linux arm-gcc, gnumake, etc.
I have a fairly complex PPI configuration but in the act of debugging it, I've dumbed it down quite a...
How does the interrupt latency compare between COMP/LPCOMP and GPIOTE? Are t LPCANADET and t PROPDLY the correct field to be looking at in the specification? The electrical...
Hi Nordic Team,
My Board: nRF5340 DK; SDK: nRF Connect SDK v1.5.0
I am new to BLE developement. I am trying to design a GATT service which can be accessed by nRF Connect...
I'm trying to use UART flow control and assign RTS CTS pin numbers.
What's the corresponding number for P0.02, P1.15 each?
And where can I find this information?
Hi,
I have used nRF52811 SoC in my custom design. In this circuit i have used SWD interface only as per reference design. I have used same SWD 10 pin connections as mentioned...
128 MHz or 64 MHz operation is mentioned in the specification (page ii). However, can MCU be capped at around 12MHz? How about the current consumption?
