Tasmota issue - Error msg 0x10-ERROR - size(69), state=4

[hsaturn]

I was too quick with my question.

After I set user and password on the client the client is connected.
But removed immediately.

Does anyone have the TinyServer running with TASMOTA clients?
Thanks in advance for every tip.

Hi Michael,

i tried the same and I have the same problem.
I looked a bit deaper in the sources and it looks like that the "Last Will" which is provided by the Tasmota Devices cause the iussue.
Sadly I found no way so far to, disable this last will stuff on Tasmota by my own.
using CallBack = void ()(const MqttClient source, const Topic& topic, const char* payload, size_t payload_length); enum attribute((packed)) Flags { FlagUserName = 128, FlagPassword = 64, FlagWillRetain = 32, // unsupported FlagWillQos = 16 | 8, // unsupported FlagWill = 4, // unsupported FlagCleanSession = 2, // unsupported FlagReserved = 1 };

Ist the code from the client function in Tiny Mqtt. Perhaps someone knows if there is an easy way to add the "Last Will" functionality.
