Hello, We have a custom board with nRF52832, using BLE, s132. I have noticed recently that in nRF Connect App (v4.29.1) usually the services and characteristics show up twice...
Hi there,
I am trying to develop a simple application that must write information within a micro SD card (nothing too fancy, it is just plain data read from the internal...
Hello!
I'm writing an application that uses MQTT to post some sensor data to a server. My networking code is basically a duplicate of this sample , except I set up the LTE...
Hi,
I added MCUboot and SMP BT Service to the OpenThread CLI routine to implement the device firmware upgrade function.
I found that after DFU is completed, the Thread...

Hello,
we want to get three different states using only one GPIO:
1. nRF52840 GPIO output driven low
2. nRF52840 GPIO output driven high (3V3)
3. nRF52840 GPIO internal...
Hi Support Team
UART20 of nRF54L15 can't work when setting P2.02 as TXD and P2.00 as RXD when I test the central_uart sample of NCS V2.9.1. I find that the SPI00 has used...
Hello Nordic community,
I'm working on a project using the nRF5340DK where I need to achieve precise control over three GPIOs with the following specifications:
P0.07...
Hello,
We are using the nRF52840 on our own board.
When I added up the current consumption at 3V, based on the datasheet, I get 14.3mA (CPU from RAM, Tx at 0dBm 1Mbps...
Hi there,
I'm using a slightly modified version of coap_client to test out network connectivity with a 1nce SIM card (USA). Essentially, I've modified it from a GET request...
