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...

I am using the LFCLK RC oscillator, 8000ms calibration interval.
Is it possible to read from some register the resulting calibration value for the LFCLK RC oscillator?
Now I work on designing a product, which is implemented by sending LMP commands to a bluetooth device with nrf51822. Unfortunately, nrf51822 liberary could not provide the...
Hello,
measuring ADC signal on P0.26/AIN0/XL2 and P0.27/AIN1/XL1 doesn't work (I get constant value from the ADC not reflecting actual voltage on the pin). AIN2 - AIN7 seem...
I need to send a disconnect command from the app layer. I've seen a few other posts that say to use uint32_t sd_ble_gap_disconnect. One post had this line of code as an answer...
I am using the RBC mesh in a networking product using the nRF51422. We would like to turn the mesh on and off at selected times, say once per hour for a minute or two. I know...
Hey,
I have been trying to set up wdt for my application which services some interrupts once in a while and advertises continuously. I put the nrf to sleep using sd_app_evt_wait...
Hello,
I'm trying to read voltage signals from a sensor using internal ADC and send them OTA. For now, my codes seems to work, but the only problem with my codes is it...
