Mqtt and Async Webserver can't co-exsist. about portenta_h7_asyncwebserver HOT 5 CLOSED

Hi @javos65

Unless you can prove there is a real bug of the library, I'm closing the issue because I don't have time to investigate what's wrong with your code. It's your job to learn why and fix it.

Good programmer is not just sitting passively, relying on other people, when getting into fatal crash. We all can learn a lot from the mistake / experience. I'd appreciate if you can share yours back here what's wrong. If it turns out to be this library's bug, we're happier to find out and fix.

Good Luck,

FYI, try the

• MQTTClient_Auth
• MQTTClient_Basic
  which are using the same PubSubClient library

from portenta_h7_asyncwebserver.

Thanks for the reply.
The used MQTT calls are a 1:1 copy of your MQTTClient_Basic.ino example, same for the Async_AdvancedWebServer.ino example. Seperate sketches work fine.
My example is your 2 example-code combined in one sketch, and combined in one sketch it fails on Mbed OS / Portenta H7.

You dont need to look or debug my code, however if you can show a working combination of the Async_AdvancedWebServer and PubSubClient in one sketch, that would be appreciated (Probably 15 minutes of work to combine you own examples ?)

I don't like and have interest to do that.

Just a suggestion for you

1. Async is better working with Async. The examples are just simple demo to show basic usage and don't fully rely on them in your use cases.
2. Use AsyncMQTT_Generic library, such as these examples as the starting point to merge

• FullyFeatured_PortentaH7_WiFi
• FullyFeatured_PortentaH7_Ethernet

You'll sure be much better if successful then.

Good Luck,

This is the right direction - thanks.
AsyncMQTT_Generic is combinable with the Portenta_H7_AsyncWebServer libraries, and seems to work in co-exsistance.
Async is definitely not advisable with the legacy PubSubClient libraries.
