I'm also fed up with repeating myself to people who dont read the documentation and insist on using the wrong calls then complaining when they "don't work"
1. Pangolin provides raw uint8_t* and length function which is 100%-compatible with every other MQTT library, so your assertion is fundamentally incorrect and easily proven so simply by looking at the API
2. If you use the above , then like all other implmentations, no trailing \0 is stored - thats coding 101. So, if you then use a specific call which requires there to be a trailing zero (like every C string function) then of course it won't work! So don't do that - unpack the payload yourself using the correctly provded length, as in any other fully compatible implementation
3. If you call client.publish("mytopic",qos,retain,payload); where payload is eiter a std::string or a String then Pangolin appends a trailing \0 so that the payload can be used by any "normal" string function - including of course payloadToCstring. If this is not what you want then don't use it! use method 1 which works the same as any other MQTT implemntation.
4. Please , don't mix and match functions that were never intended to work together and then complain - wrongly - that they don't work and then "badmouth" the product - incorrectly - because you either didn't read or don't understand the documenation.
