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 all,
I've spent 4 days now (!!) on getting a "Hello World" project to work in eclipse with GCC. I guess something around the startup-code is setup wrong in my very simple...
Hello, I'm using nRF51822-mKIT for a research.
To verify ADC readings from analog input, I've connected P0_5 to GND and ran the following code:
uint16_t adc_result;...
For my project I would like to use this bluetooth module: freqchina.en.alibaba.com/.../Fingertip_size_nRF51822_Module_Ultra_Low_Power_Bluetooth_4_0_Low_Energy_RF_Module.html...
I am trying to connect to a peripheral through s120 central and vendor has a 128 bit fixed UUID
I am trying to add it on central using sd_ble_uuid_vs_add(...,...) but it...
I am trying to develop an application for the Android that will communicate via BLE to a Nordic device. I'm able to read the characteristic's value by
BluetoothGattCharacteristic...
I'm using nRF51822 SoC and I have a LIS3DSH accelerometer connected to the ship via SPI bus . I used the SPI master example . So i used the switch_state() function then took...
Hi, I would like to know how I can immediately detect when a connection link is loss either from the central or peripheral. I need to know which error or notification to look...
Hello.
Here was the question about S120+DFU and Petter Myhre said that Nordic ready to release the new S120 version with the peripheral mode support, so making DFU OTA will...
Today I tried to update the SoftDevice of my project. I was working with the experimental NUS example with the old S310 SD (1.0.0). Because I want to communicate thru ANT...
Hello everyone,
I'm developing a security scheme in which the firmware verifies that the nRF51822 is the same as the one in the factory to which the firmware was installed...
Hi -- Can I run direct test mode on the nRF51-DK?
I've found the Direct Test Mode window in nRFgo Studio, but my board isn't available in the "Set up on ... " pulldown...
Hi,
I'm trying to implement a device including a PWM counter and a high resolution timer working with softdevice stack 110. Per the examples I got from this site, I'm using...
