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...
Hello,
I just received my Thingy:91X which I purchased through DigiKey. I am trying to connect it to hello.nrfcloud but I keep getting the following message: " The fingerprint...
With reference to the Thingy:91x reference design, I see that the LNA (SKY65943-11) on the GPS signal path is powered by one of the switching converters from the nPM1300:...
Hi,
I'm using cdc_acm to create two COM ports on a PC -
// USB support
& zephyr_udc0 {
cdc_acm_uart0: cdc_acm_uart0 {
compatible = "zephyr,cdc-acm-uart" ;

In other words, is it safe to assume that in various BLE events, conn_handle is either invalid (0xFFFF) or between 0 and (CENTRAL_LINK_COUNT + PERIPHERAL_LINK_COUNT - 1) ...
I'm digging my way through the examples, SDK code, etc, and I'm curious if it's possible to light an LED if the nRF52832 is reaching an error status. This is mainly so I can...
Hello,
I am seeing a strange problem with the nRF52 RADIO peripheral: sometimes a packet will be received that is corrupted, but the CRCSTATUS register indicates the CRC...
My company is developing an embedded product based on NRF52 and until now we are
using Master Control Panel (MCP) to test BLE communication. MCP is a great tool
but we need...
Hi,

Hello again,
fortunately I made some progress using the IoT-SDK v0.8.0 on nRF51. I extended the MQTT-example to my needs, but there are still some questions.
