I am looking for cheapest (up to few hundred USD) and simplest Arduino basic solution to track real-time RFID tags distance (also direction if possible) without additional...
Hi all,
I am new to Nordic semiconductor but I could be interessed by nRF9E5. To check if it could fit my requierement, I would like to know if it possible to configure...
Hi,
I am using ADC without external reference and no analog input in order to measure the battery level with a timer (code at the end).
I am also reading several ports...
Hi,
I'm programming the nRF51822 and save some user data into the FLASH by using pstorage_update . It works fine if I set system off mode, and wake it up. I can read back...
Hi,
I have been using nRF51822 with my Android app using Android's Bluetooth Low-Energy APIs.
In order to get more details, I am currently working on integrating the Android...
I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...

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...
