Hi everyone, I am looking for an external oscillator on the nrf52840 DK that can take its own power and is similar to a push button that can make a voltage change on the GPIO...
Hi!
My BLE peripheral needs to change its "static" passkey under certain circumstance.
However, when I attempt to connect after setting it, I get a PM_CONN_SEC_ERROR_PIN_OR_KEY_MISSING...
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...

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...
