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 am new to eclipse on windows.
I have bought the PCA10040 board.
I have installed eclipse and GNU ARM Eclipse 3.1.1 plug-ins.
Copied the NRF52-SDK into workspace...
Hi developers,
I am trying to collect data from an AFE (ADS1298) and could get some values. Inorder to check the accuracy I need to plot this value. I am programming this...
Hi,
I am running the nRF51822 from a coin-cell. I need to measure the cell voltage. Until now, I have attached VDD to an ADC pin with a voltage divider and a capacitor...
Hello~
In my production line use jig contact my PCBA, and use Jlink connect to Nordic 51822 download FW, but I found sometime can use 500kHz and sometime can't use, just...
Hi
I am using nRF52(PCA10040) as a sniffer dongle, but it seems the sniffer mode cannot work, and shows the error log: "INFO: Error on port xx. file: Packet.py, line 245...
First step of trying to integrate S132 to a small OS is failing completely.
When I use SVC the system ends up in hanging in hard fault.
The SoD handler ends up trying...
I am testing to develop an application that sleep (system-on mode) for most of the time, and it wake-up periodically to send out somethings.
As I would like to lower the...
Hello,
After when I download the protocol stack(S132).The target is NRF52832 chip,tool is J-link OB.
I choose to recover nrf52 ,then prompt unable to fine or open the...
Hi,
In ADC, we would be using the internal voltage generator as the reference voltage. How stable is the voltage coming out of the reference generator. Would it be always...
It appears that, if I wanted to write characteristics to my BLE device, I can utilize the writeCharacteristic method of the BluetoothGatt class. Is this the right way to go...
Hello,
I am currently for a quick solution to test NRF24LE1 compliance to FCC. Can you provide me with any code if possible? As i could see from the website only an application...
Hi,
We can utilize the 31 bytes of advertising packet as well as 31 bytes of scan response packet which in total makes it 62 bytes of advertising data. What is the effect...
Hi dear Nordic Engineers.
We going to move from FN-LINK (Realtek) I.C. BLE to nRF52.
FN-LINK uses HCI (UART) BLE the Interface to communicate with our embd. LINUX.
How...
Hi all,
I'm using pca10040 board with sdk version nRF5_SDK_11.0.0-2.alpha_bc3f6a0.
There i'm using example code of spi handling. Instead of nrf_log_printf i changed...
