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...
i made this project to try to create RSC service on arduino

unfortunately the server starts but i'm not able to...
Hello,
We are using the nrf connect Android app in order to scan and connect to ble peripherals.
The scan procedure is executed perfectly as we can identify and connect...
Hi In v5 one can advertise in le_coded and then a central can connect off the resulting AUX packet.
For the AUX_CONNECT packet the inter-packet delay is T_MAFS which is...
When I read Objective Product Specification v0.7.1, it seems external pull-up resistors are required.
However, when I use TWIM without them, it works out.
Do I need...
Hi Everyone,
I am using nRF52832 with SDK v14.2 and SD v5.0.0 on a custom chip.
Recently i included DFU support to our application. It turns out that secure bootloader...
Hi, I'm new to nRF52480 and Nordic SDK. It is first time for me when SDK has one big config file sdk_config.h. I started playing with examples (LEDs, serial I2C) and get it...
I am developing a PCB that contains this schematic, I can run the sw code on the nrf52832 and use the pinout, but I can't connect to nrf52832 via ble communication. I think...
Hi. My product uses nRF52840 as a beacon transmitting every 3 seconds at max power of +8dBm fed to an antenna of gain 2dBi. Is SAR testing needed for my product? Product is...
Hi,
In our application Csense driver is used.As it can be implemented using COMP and SAADC,due to mentioned limitations for COMP we opted to use SAADC.Only AIN7 is used...
Hello, I have a time critical project that requires a unique service routine, thus a specific 128 bit UUID. I am following the tutorial on custom services but it does not...
I need to make something like this and need that baudrate which are configurated in smartphone BLE app that this value be and on NRF528XX uart baudrate.
For example when...
What is the recommended way to flash firmware onto the stand-alone microcontroller. I have never dealt with a stand-alone microcontroller before.

I am trying to get buttnless DFU working on the NRF52832_XXAB which only has 256K Flash and 32K RAM.
I have buttonless DFU working on the nRF52 DK which has the larger part...
The above is the waveform of data pin and chip selection pin.(The yellow waveform is the data pin waveform. The blue waveform is the chip selection pin waveform. And chip...
Below is a picture of advertising event current waveform:
The TWI current consumption is upto 2mA, I change the peripheral from TWIM to TWI, the current is exactly the...
