Anyone know of a breakout board for a SPM0404UD5 or any other similar ultrasonic MEMS sensor? I want to build a ultrasonic detector so I'm looking for something that can detect the presents of ultrasonic sound (if you could call it that ).
Thanks
Sorry, my bad. It is clearly a gateway log.

The first line here shows that the gateway received a message from node 3.
The message is a Find Parent request, which means node 3 is asking for the gateway.
The last line is the gateway sending a response. The ! before TSF and the st=NACK means that the gateway sent the message, but the gateway did not receive acknowledgement from the node that the node received the reply.
The most common cause is unstable power supply. What capacitor(s) are you using? (On the Raspberry and on the node). How is the nrf powered on the node?
If you haven't already, see https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ for the most common problems and how to troubleshoot them efficiently.
@torfinn These settings should make it work, regardless of which version you buy:
// If you are using an RF-Nano, you have to switch CE and CS pins.
#define MY_RF24_CS_PIN 9 // Used by the MySensors library.
#define MY_RF24_CE_PIN 10 // Used by the MySensors library.
// Enable and select radio type attached
#define MY_RADIO_RF24
#define MY_RF24_PA_LEVEL RF24_PA_MAX
// Mysensors advanced settings
#define MY_RF24_DATARATE RF24_1MBPS // This datarate is supported by pretty much all NRF24 radios, including the RF-Nano.
@mfalkvidd I tested shorts with my multimeter and didn't find any shorts. However I should receive next week some new of these chips and I will try to solder them new. Let's hope that that's the issue!
A datasheet for the new nRF5340 is now available: https://infocenter.nordicsemi.com/pdf/nRF5340_OPS_v0.5.1.pdf
It has some improvements, but some of its competition seems to be much lower power.
@sundberg84 Yes, but I wonder if it will also work if I use the regular (round) THT pads from the Pro Mini (as the cheapest and most widely found Pro Minis seem to be like these)
I'll probably just try it I guess, but of course have to adapt my PCB accordingly to get the castellated half holes. Hope my PCB manufacturer knows what to do with the KiCAD file.
