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...
nRF52 SDK13 S132.
For example, I have handle from 0x180A service.
I want to read characteristic 0x2A24 from here.
How should do it?
In the watch window I can see event...
We are interfacing to a SPI Flash MX25R8035F.
When attempting to read 1 page of 256 bytes from the chip we break the read command up into 4 SPI Commands.
1) Read the Status...
Hi,
I`ve made fixes in SDK 13.0.0 files described below:
nrf_section.h : to supress gcc warning: invalid suffix on literal; C++11 requires a space between literal and...
When I set the PWM driver for very low frequency i can see how it blinks, the thing is that it always blinks where it's more or less 70% of the time ON and 30% OFF .
When...
Hello,
Working on a project using the pairing and bonding security model, I would like to filter out of a central's scan all already bonded peripheral devices. Or, I could...
For some reason I get a softreset instead of a sleepmode when I call sd_power_system_off();
Device: NRF52832
SDK: 12.2
S132 v 3.0
I do clear all gpiote interrupts...
Hi, in our project, we need to apply 51822 as MCU to control other devices. But we need 2 USART ports. I wonder is there any product in nRF51 series that can do this. Thanks...
I got some SPI flash memory that is capable of generating interrupts in order to save some program/erase time and power consumption. The only drawback is that interrupt is...
hi,
the main function could not execute with softdevice. before it was working. but i have added some code that mean pstorage_store(). already, it has pstorage_load() and...
Hello, I got this error:
Error: L6221E: Execution region RW_IRAM1 with Execution range [0x20003120,0x200046a8) overlaps with Execution region ER$$.ARM.__AT_0x20003000 with...
Hi,
I am using the nRF8001 with a MCU as the application controller. Everything is perfect when I just use commands/events between them. I can send and receive data smoothly...
Hi,
Peer A is bonded to the device. Now device has Peer A bond information. For some reason, Peer A has un-bonded the device. As device doesn't know this it still keeps...
I would like to under stand Nordic's strategy for compatible hardware for use with nRFConnect V2.
We have a customer who wants a desktop BLE app and we are considering...
Hello,
I have a single module of NRF51822, not any DK-board. I'm using GCC4MBED compiler and ST-LINK V2-1 programmer.
I would like to try the HID Keyboard Application...
