Issue
When i use mqttjs wss to connect to old broker, it return [ 0x22, 0x02, 0x00, 0x00 ], but the MQTTJS throw error , the message is connection error: Error: Invalid header flag bits, must be 0x0 for connack packet , I know that from 5.0.0, it will check the format of message according to the MQTT Official Document.
I searched online but couldn't find the answer.
I cannot modify this custom MQTT broker either.
So, my question is : how to close the format check logic?
Beta Was this translation helpful? Give feedback.

The parsing/encoding of mqtt packets are handeld by mqtt-packet, dunno if there is an option to disable this check there, you should check or maybe @mcollina knows
