I tried the UIFlow "DAC beep" without success. Would be great to be able to use the Core2 speaker.

Thank You

I have found the problem:
In RUN mode, the block "Set Communucation Channel" is not executed. The units work on the default channel 6. I had selected channel 1, as it is emptier for me. After downloading into the device, however, the channel block was executed and the device ran on channel 1. That is why the devices did not find each other. After I changed the script to channel 6, it works as it should.

I am also stuck trying to get this to work. Some research reveals that there may be a ca_certs parameter required to include Amazon's root CA. I've tried it like this but no luck:

while True: output.setText('Setting up mqtt') m5mqtt = M5mqtt('m5stick', 'a2zey9c7ts6fdf-ats.iot.us-west-2.amazonaws.com', 1883, '', '', 300, ssl = True, ssl_params = {'key': "/flash/res/priv.key", 'cert': "/flash/res/cert.pem", 'ca_certs': "/flash/res/ca.pem"}) m5mqtt.subscribe(str(''), fun__) output.setText('starting mqtt') m5mqtt.start() output.setText('publishing hello world') m5mqtt.publish(str('test'),str('hello world')) output.setText('sent hello world') wait(1) wait_ms(2)

Can anyone from m5stack confirm whether ca_certs is a supported ssl parameter?

If you download this code to device you should add block to connect to your wifi network

advanced -> network -> wifi connect

or

advanced -> network -> connect to wifi ...

@peter
now I know that every Device has 2 MAC-Adresses. The Adress with showed by MyMacAdress-Block and that Adress -1. It receives on both Adresses and send with the lower Adress. I tested it with 3 M5Stck C Firmware 1.7.0 and 1.4.5.

Has that any sense? I see that the first time.

@dario Thanks!

Tnx sodoku.

If found the Problem was only in my head. It works with TX-Pin 1 and RX-Pin 3!

Great thanks - didn't try play due to this comment in the documentation
"MQTT program must be downloaded to use!"

Have tried it and play seems to work ok. I seem to have to reset the device though to download a new version of the code, but the good news at that after reset it goes back ok into the cloud connect mode ready to receive a new version.

I have found that I can do this - programatically using
import machine
machine.reset()

Just wondering if there is a way to avoid having to do this step when operating in play mode.

Found the solution. Within the HTTP Request it was the wrong method for the integromat.com example. It has to be POST not GET. This way it works as expected.
