MQTT and binary data using AT commands

It is possible to use binary data in QMTPUB command and QMTRECV notification on M66? Could you provide some examples?

I would like to use M66 to communicate with MQTT broker where data is binary. I know that MQTT specs support it, but I’m not sure that MQTT implementation in M66 allow this.

I’m looking for GSM modem with MQTT implementation.

@dmajewski I have not tried it with MQTT stack of MC60, but have sent and received binary data to a MQTT broker via SSL functionality of MC60 module and to me there should be no issues in sending binary data via QMTPUB command/
