I installed firmware 1.1.1.9 on my wizFi360. I’m trying to use AT+MQTTPUBSEND to send binary data but it always returns error. is this command handled by this firmware?
Hello, this is WIZnet. I am attaching the screen that I tested here.
Did you enter the length of the following data for [AT+MQTTPUBSEND=]?
(ex. AT+MQTTPUBSEND=5 > 12345)
You should enter the length in advance and then transmit data of that length.
Please refer to the command document for more details.
AT+MQTTPUBSEND return always error

You’re using MUXID, then the command is [AT+PUBSEND=ID,Legnth ].
The document doesn’t explain it well enough. We’ll fix that part.
example is here.
