Can't get a Nano IoT33 to work

Community Help With My Project
1

Hello, I have a Nano 33 IoT and can’t get any connection working with Cayenne. I’m not 100% clear which example code I’m should to use as the Nano Iot33 isn’t specifically listed on the website, but I’ve ended up trying all the example codes for all shields and none of them have worked for me. If someone could tell me which one to I meant to be using it might help me troubleshoot further. I have been trying with Wifi Shield, Wifi101 and MKR1000.

I have reinstalled everything (SAMD boards, libraries, IDE.) multiple times, but still nothing seems to work.

I’m also not getting anything on serial monitor if I put Serial.print code in void setup or loop.

I have seen some mention that I need to include WifiNINA library with the package, but when I try include that I get errors compiling listed below.

Arduino: 1.8.15 (Mac OS X), Board: "Arduino NANO 33 IoT"

Error compiling for board Arduino NANO 33 IoT.


This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

any help would be hugely appreciated. I just purchased 5 x Nano IoT 33’s and would love to get them working with cayenne rathan than using Blynk

3

can you do one thing? can you try connecting arduino Nano IoT 33 to your internet using a basic code and share it here. I will add the MQTT code.

4

Sorry I should have also mentioned that I have successfully connected the IoT33 using WifiNINA and I’ve also connected it using Blynx.

I’m not sure what basic code you wanted me to use but here is the WifiNINA example code to connect to a WPA network and this connected without trouble.

/*
 This example connects to an unencrypted WiFi network.
 Then it prints the MAC address of the WiFi module,
 the IP address obtained, and other network details.

I have not tested the code, you can do the required changes :-

Amazing, thank you. It worked.

Can I ask why you think the standard examples didn’t work?

And are you going to include examples for the newer models on the website in the future? It was a little confusing to not see my device listed and very little explanation.

Like the above the code, you can use the code to connect to internet and combine it with MQTT code to connect cayenne. These way you can connect any device to cayenne.
