I downloaded the BLE beacon app S110 v7.1.0 to a nRF51-DK board. The current measurement pins were attached to a 10 Ohm resistor.
I observed the AC-coupled voltage at one...
Hi. We've got a chip with a code QFACA10. I am trying to find out if there is the internal pull-down of SWD line or not. It seemed that adding an external pull-down had positive...
Hi all,
I want to know the effect on power consumption of pins input buffer on and off, does there are big differences between them?
Another question is, since there...

I have the nrf51822EK and trying to make it report the speed/cadence of a bike. So far the design is to report the speed every 1 second as a BLTE peripheral device automatically...
Hi,
the ANT protocol defines the channel message rate in a range from 0.5Hz to above 200Hz, with the upper limit dependant on the specific implementation.
What are the...
