Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

Hi,
I found that the NRF 54l15 can only estimate distance based on channel sounding and RSSI. On the bluetooth website it mentioned channel sounding accuracy being around...
Hello,
I'm looking to get XInput working on the nRF52840 so that our device can appear as an Xbox-compatible game controller. I'd appreciate any guidance or recommendations...
Hi all,
It is a common convention to configure the I2C SCL signal to be push-pull instead of open-collector if there are no other I2C masters in the system (saves a pull...

I have finished developing an application, utilizing the nRF 9151 DK, and I am now working on transferring the firmware to a custom board and testing it. However, when creating...
I can flash the chip. I can run the debugger. I can go to the connected devices, select the device, go to the little "plug" symbol on the RTT, and select it. That brings up...
Dear Forum,
I have an nrf54l15 device and I would like to send a pure sinusoidal tone and measure the phase difference, retrieve I/Q values at the other device. This is...
Hi! I am designing a nRF54 based motion tracker that has an IMU onboard which can take an external clock signal for improved timing accuracy. Initially I had thought of just...
Hello,
I am having an issue using GPIO P0.03 as a button input in my design. Unfortunately, I did not notice that this pin is marked as a dedicated pin for the GRTC peripheral...
Hello Nordic,
We have recently purchased an nRF52840 Dongle. We were able to sniff the BLE packets over the air. So it is found that all the packets that we are able to...
