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'm attempting to wake the nrf52480 from it's sleep mode using a button input and sequentially send the command normally associated with that button without requiring...
Hello Experts,
We need to get an RF certificate for our product with nRF52840 (it's actually nRF52840 USB dongle).
In our case, the BLE stack is initialized in the central...
The instructions are wrong -- I have verified with 3 different boards that Step 3 does not work.
Step 3 states: Click the large “+” sign on the top left to add your new...
I have written a UARTE driver, to conform to the kind of API we need, for NRF52840. It is very nearly working except that it drops single received characters and I'm trying...
Hi there, I'm trying to guesstimate the best that I can, the amount of power it would take to transmit roughly 10 kbit/s of data through LTE-M on the nRF9160. I'm just looking...
Attached is a nRF52840-DK project and an Xcode project with iOS and macOS targets. When I run on macOS the L2CAP channel is opened. When I run on iOS the L2CAP is not opened...
