I am using light_control example from Mesh SDK and I need to get something that identify my device in mesh e.g id, address. I would like to send some message to the...
Hi,
This is somewhat tricky question.
In my custom board application program using nRF52832 chip,
I used uart initialization function (e.g. uart_init()) and printf...
Is it possible to use a Nordic nRF52840 DK and a personal BLE board to run the throughput example? What types of modifications would have to be made to both boards?
Hi,
after setting up the LPN-example like described here I can establish a frindship relation.
When I measure the current I can not get lower than 40uA.
I use a Multimeter...

Dear Nordic experts,
I am trying to profile embedded S/W on a custom board (call it board #1) with a nRF52840 on it. On this board the trace pins TRACECLK and TRACEDATA...
Hi,
I'm currently trying to evaluate the nRF9160 for one of our projects.
One key requirement is the power consumption when using eDRX.
I have tried profiling the...
I noticed that passkey entry for BLE pairing is usually implemented by the device operating system outside the nrf_connect app. Is it possible to do passkey entry inside a...
