It seems as though DHT.acquireAndWait() is causing issues on an Argon with Device OS v1.2.1-rc.3. I was able to reproduce the issue even with the DHT_simple example from the library. Whenever this line is executed, the device begins an SOS red led sequence with 14 flashes following the SOS. Has anyone else experienced this?


#2

That is a very strange panic code for that library

https://docs.particle.io/tutorials/device-os/led/argon/#red-flash-sos

The library doesn’t really have any busines with that.

Have you tried with any other device OS version?


#3

Yes. It doesn’t have the same behavior on 1.1.0-rc.2 with the same example (or custom firmware).


#4

Can you file an issue report at https://github.com/particle-iot/device-os/issues about that, please?

You may need to reference this thread and explicitly state that it’s not an issue with the library as it used to work prior 1.2.1-rc.3

Thank you, @ScruffR.

Just got the same issue after updating my Argon to V1.3.0-rc-1 from V1.1.0

Hi there, I’ve been brought to this thread by a similar issue on my Photon.
I’m using the PietteTech_DHT library on a suite of Particle boards including Photons, Xenons and an Electron. The Photon in question just updated from 1.1.0 to 1.2.1
