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.

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...
On my peripheral I filter the devices connected and refuses them when not bonded.
When a device not bonded tries to connect to the peripheral, it forces the disconnection...
Hi,
I am using nrfsdk11 nrf52 and s132 soft device. In my code,I am doing this in main();

Hi everybody,
I will to use the nRF52832 QFAA for a drone, and I carried out this schematic for this chip.
I have two questions :
For the capacitor C6, which value should...
I'm trying to start my app from the bootloader, which is funcionally basically the same as the one in nRF5_SDK_11.0.0_89a8197.
To start the app I call bootloader_app_start...
Hello.
I use nRF52832 and its dev board, S132 soft device. nRF5 SDK v14.2.0 is the version number.
I want to change some manufacture specific data from mobile app. Like...
I am working on the nrf52840 kit with the ble_app_beacon example, compile and download the code successfully. But I don't know how to test whether the kit is advertising,...
I have my own hardware design with the nRF52840 on it. I more or less copied the whole radio/antenna part from the dev kit reference design. The blinky example works fine...
After checking and searching, i found this ble_gatts_conn_cfg_t::hvn_tx_queue_size should be the key to set it. In my custom project (SD132 V5 + SDK14.1) the only setting...
Hi
I'm using IAR Compiler and need to generate some PWM outputs. I tried to use the example code from the pwm_library. But the compiler is generating an Error on the macro...
I am using PCA 10040 development boards with soft device version s132_nrf52_3.0.0 to investigate Central/Peripheral communications.
A PCA 10040 acts as a Central making...
Here is calibration of UART data using ADXL345.
and the data is followed by x, y & z value, for example x = -42, y = 20, z = 268. and then after calibrated 10x which is...
We are upgrading an existing product to use Bluetooth instead of the parallel port.
It must support >20kbit/sec communications between the device and the host PC.
We...
