Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hello,
I want to request AGNSS information from nrf cloud services using my nRF9151DK board. As a first step, I flashed the nRF Cloud multi-service application onto my DK...
Hello,
I just received my Thingy:91X which I purchased through DigiKey. I am trying to connect it to hello.nrfcloud but I keep getting the following message: " The fingerprint...
With reference to the Thingy:91x reference design, I see that the LNA (SKY65943-11) on the GPS signal path is powered by one of the switching converters from the nPM1300:...
Hi,
I'm using cdc_acm to create two COM ports on a PC -
// USB support

I can make the RTC work with interrupts and __WFI(). I absolutely can't get events and __RFE() to work for the RTC. However, it works if I replace the __RFE() with __NOP(...
All of the FDS examples I have seen seem to ignore the fact that fds_record_write() just queues a write, and therefore the data pointed to by p_record.data.p_data needs to...
Hello,
I am having a strange issue. We are currently in pre-production with our product which uses the NRF51822. Just for context, the production tests use the UART peripheral...
Hi all,
I currently need to implement 3 channels of analog inputs on my nrf52, but when I attempt to compile the project, I get the following errors:

I need to get rssi in dongle side and I found ble_gap_rssi_start and ble_gap_rssi_stop...
Hi,
Is it possible to write/read the flash memory, from within the interrupt handler of GPIO? I used an push button connected to a GPIO to wake up the ble chip, then read...
Hi,
Does nRF5340 (or any other nRF52XX) support natively ISO7816-3 (SmartCard)?
"Natively" means using USART or any other way(hardware of official software) other than...

Hello Nordic,
I worked with the interactive PyACI during several months by using my PC (running the interactive PyACI) connected through usb to a DK used as provisioner...
Hello,
We've recently migrated from SDK version 15.2.0 to 17.0.0 and noticed an anomaly with the clock driver. If the watchdog is started, then after any soft reset (through...
Hello! How can I measure the heap size (total and free space) at runtime?
Right now I'm working with some legacy code that makes a call to mallinfo()
That call returns...
I am testing "nRF5_SDK_17.0.0_9d13099\examples\ble_peripheral\experimental\ble_app_cli" example.
Do I need 2 boards to run this example ???
