Hi all,
I'm currently trying to get the UART example (no SoftDevice) to work under Segger Embedded Studio. What I know is, that retarget.c is used to redefine the neccesary...
Hello,
I've been implementing DAC control trough SPI and DMA using the NRF52 and it is working nicely. During development however I encountered what i think is a bug in...
Hello
i am using the NRF52 EvalBoard and a ADXL362 EvalBoard. I am trying to read every 100ms the FIFO buffer of the ADXL362. Below you can see my register configuration...
I can't get NRF_LOG working with SDK12.3.0.
Using the same main.c and sdk_config.h from SDK12.2 - here NRF_LOG is working well - I get no messages in J-Link RTT Viewer with...
I have made following connection between nordic device and external sound sensor:
VCC--> 5V

I would like to...
Hi all,
Can you give me an estimate about the power consumption required for the update Fw on OTA.
Our product has a solder batteries, so it's important know if in his...
I am using proximity profile using NRF52 DK.When i started measuring power consumption it is not at all coming less than 2mA.
In order to make as low power ,is there any...
Hi all, I am using a nRF52 in PTX mode to request a progress status from another nRF52 in PRX mode every two seconds. The PRX is updating its internal status every 0.25 seconds...
