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...
When use the "nRFBeacons" app to update the info on my beacon the following happens:
Go to update tab.

Hello,
I was reading some SDK 15.3 code, there's something like this:
__STATIC_INLINE void pwr_mgmt_sleep_init(void) { #ifdef SOFTDEVICE_PRESENT ASSERT(current_int_priority_get...
Hi all, I'm developing nRF52840-DK to use it as an central device.
Base example is usbd_ble_uart: I'm going to communicate with peripheral device using BLE, and control...
We have a product that uses the nRF52840. We have seen that very rarely, unexpected resets happen with the reason being OFF. We have yet to encounter this issue in a lab setting...
I'm using the SPI manager to talk to an ILI9342 graphics IC. I need to toggle an IO line during a transaction or in between transfers. For the first byte the line will be...
I am trying to enable DFU over USB with the nRF52480, while keeping the possibility for Serial communication. I got a working example with both separate, however when I try...
It's my mistakes.
1.I want to measure temperature from DS18B20,but I don't confirm the capable of the pin - P0.05.Because it's Analog ,but DS18B20 is Digital.
2.I set the...
Hello, I'm getting started with a nRF52832, I've got the SDK 16.0 installed and what I think are all the latest packs installed. I try to build the examples\ble_peripheral...
Hello everyone.
I'm trying out the "Zigbee Multi Sensor Example". infocenter.nordicsemi.com/.../zigbee_multi_sensor_example.html
I have 2 nRF52840 devices.
I wrote the...
When my program starts, I set up a watchdog timer for 100 milliseconds and I start a repeated app timer that runs every 90 milliseconds to feed the watchdog. I use the app...
I'm trying to send data via UART from a NUCLEO-F401RE to the nRF 52840 DK. But the data I send is not comming through correctly. For example when I send 3 the nRF prints 32...
I have an existing product to which I need to add SPI to get Wifi compatibility. Basically the Nrf52 is acting as central and passes BLE events on to an ESP32 with Arduino...
Hi.
I have nrf52840-dk board. i tried the UART example from the peripherals directory. it works with the default, if i open a console on /dev/ttyACM0 and on /dev/ttyUSB0...
Wanted to ask if there is any example on configuring the GPS into single shot mode.
I know the asset tracker can operate in continuous_mode and continuous_power_saving_mode...
I am attempting to use SDK15 with the nrf52832 to communicate with multiple sensors over I2C. However, in the twi_sensor and twi_master_using_nrf_twi_mngr examples, as well...
I am using the nRF52840 with the SoftDevice disabled to run a proprietary RF protocol. For much of the time, I have the radio in continuous receive mode by making use of the...
