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

Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
Hello everyone,
I'm trying to interface a NiceRF LN610 LoRaWAN chip to nRF52840 via UART. Initially, I tried communicating with the chip using CP2102 USB-to-TTL module and...
Hi,
In order to measure the RF power, I measured the RF power by radiating inside the RF shield box.
But there is something strange.
The position between the device...
Hi ,
I want to develop the firmware to read the nfc tag and read the sensor data send to the application via BLE I have read many post regarding nfc . Let me explain what...
Hi,
I am working on temp. sensor with nrf52832 dev kit for firmware testing and development and also using nrf52810 for product testing.
in my code, I merged twi communication...
hi,
I want to develop a project based on ble beacon mode and ble app hts code.
and I am using nrf52810. so will it work if I merge both codes and use for this project...
I know that nrf_cal_set_time() from the nrf calendar example is NOT meant to be called on a regular basis / should only be called to update the time being kept locally to...
Hi,
We are looking for a guideline to trigger GPIO and SAADC sampling at the same time.
Our purpose is to sample every 20 m
Hi,
We are looking for a guideline...
Hi, We have a DFU OTA process that was functional, but updating our softdevice to s113 7.2.0 has left us with a problem - since the softdevice does not exist in the nrfutil...
Hello.
I am doing a small project where nrf52 reads data from a BME280 temperature sensor via SPI and sends it using ESB.
I have no experience with radio, so I use a ready...
I would like to use the NRF24L01+ from a 3v coin cell, but interface it over SPI with a 1.8v-powered microcontroller. Assuming the uC is tolerant of the NRF SPI outputs, I...
We have a application where data transfers happen through a mechanism where the external client does a write-without-response to send in a command. The response to the command...
I am busy with my first BLE project , programming a custom service for both pheripheral and central role. I have already finished the pheripheral service, using a custom service...
There are other GPS modules on the market which can give information like "the device is within 10 meters of the given coordinates". Is there a way to either get this information...
Hello,
i am using AES CCM encryption available in nrf52832,
my data which need to be encrypt is same every time. data will encrypt and 4 byte will add at the end of...
Hi all,
I am working on a project with the nrf52832 and I am using softdevice S132 6.1.1. After creating my desired flash layout (with some help on this forum, thanks!)...
