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:...
Hello,
After i disable SD i try to count ticks on TIMER1 from RTC1 via PPI.
Timer1 is configured property but TASK_COUNT don't increment cc.
I see that event TICK on...
So. After countless hours of messing around, reading SDK, examples and stuff I'm begginning to feel kind of frustrated. I want a microsecond timer. For that I tried a number...
Hello,
I use nrf51422 for my project. I have to collect data via BLE nus from phone, but after that i don't need SD anymore. Can i use blocked hardware, like RTC0, after...
