Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hello,
I want to request AGNSS information from nrf cloud services using my nRF9151DK board. As a first step, I flashed the nRF Cloud multi-service application onto my DK...
My nRF51 will occasionally lose connection to the computer, and I have to disconnect and then reconnect it before it will work. How can I reset the device dynamically, without...
I'm trying to compile a project I have for nrf51 on nrf52. I am running into errors with macros not being set.
For example:

Hi,
I'm working on a sensor application that sends out fairly large quantities of data via BLE notifications. I understand how bluetooth works and have read and followed...
Hi,
I'm currently testing ble_app_uart on nRF51822 custom board. I connected it to nrf51 DK P19 and was able to program the hex file successfully.
But it doesn't run...
Hi, In your documentation you specify the maximum CPU temperature 85 DegC.
What problems could one expect after this point?
How much safety margain du you have on this number...
I'be been reading over and over the datasheet but cannot see how to dissable Enhanced ShockBurst features for my application which only requires basic one way radio.

Hello,
I'm trying to program that module, but i can't do it correctly.
I'm using a program that works fine in nrf51 DK, but when I program this in ptr5518 my smartphone...
I want to port either the S210 experimental DFU over ANT_FS to serial DFU or the S110 dual bank serial DFU project to be S210 compatible.
I'm using S210 V4 and SDK 8
