Hello All,
I am trying to interface an analog sensor with nrf52832, whose analog values have to be converted using SAADC and has to be sent over SPI to another chip. But...
I am testing the NR52832 using a BMD350 module on a custom made board.
Using the SPIM i faced the problem that i got an extra 500uA of current randomly. After trying to...
Dear Nordic,
We are using NRF52832 + RFX2411N for our product, and for lower the power consumption. we wonder if there has any way to know the CONNECT_REQ event.
In advertising...
After some time debugging an issue I had, I found out that my code was setting the I2C interrupt priority to 0, and at the same time that I'm running a Soft Device on my nrf52832...
Hi,

Hi Dear nordic employee
I want to test the accuracy of my external LFCLK,
1、I enable the nordic RTC
2、set the prescaler 31（32768/32=1024），1/1024 second per step
...
The temp accuracy is stated at +/-5C. Does that include using piece-wise linear terms for accuracy? Is there any data on accuracy over a narrow temp range such as 0-40C? ...
Hei, I couldn't really find a question regarding this use-case.
I'm hoping to interface a USB (2.0) charging capability to my design and thus I need to have a communication...
Hi Nordic,
Does FDS affect PPI ADC acquisition when writing data? The test found that once the FDS is written to the data, the ADC data returned by the PPI ADC is fixed...
