Hi all, I'm working with RMT, especially the receive function; I'm missing something.. :shock: once it enter in the part items = (rmt_item32_t *) xRingbufferReceive(rb, &length, portMAX_DELAY); in case of no items, the loop stucks until "portMAX_DELAY" unlock it.

Re: mqtt ssl example certificate error

I copied / paste only the certificate without renaming any item in the mqtt/ssl example and now I got the same error: verification info: ! The certificate is signed with an unacceptable key (eg bad curve, RSA too short). So probably I did something wrong before this. How did you fix this? Did you mo...

Re: mqtt ssl example certificate error

What do you mean? Did you get the same error?

Code: Select all

failed to verify peer certificate
verification info: ! the certificate is not correctly signed by the trusted CA

Re: mqtt ssl example certificate error

The error is the same I got from https://test.mosquitto.org/.

If you download the mosquitto.org.crt (PEM format), and try the mqtt/ssl example you should get the same error.

Could you try? Maybe there's something wrong in my config file.

Thanks

Re: mqtt ssl example certificate error

Thanks for reply;

I'm trying with my own broker and certificate, but got the same error.

How can I "fix" the certificate in order to be trusted?
Or how can I "tell" to the esp to trust this certificate ?

mqtt ssl example certificate error

Hi, I'm having some trouble with mqtt ssl example. If I test it with the default broker "mqtts://mqtt.eclipse.org:8883" and default certificate "mqtt_eclipse_org.pem" It works correctly. If I change the broker with mqtts://test.mosquitto.org:8883 ( https://test.mosquitto.org/ ) and change the certif...

Re: Button counter with interrupt

Sorry for that. I was wondering if this approach is correct. I want to know when a button is pressed ( i.e. for 3 seconds and when it's pressed for more than 10 ). I could poll every second and check for the status of the GPIO, or I could use interrupt. My question is: when the interrupt is triggere...
