MQTTInspector

A general MQTT testing app for iOS (iPhone and iPad)

Features

• Supports all MQTT features 3.1, 3.1.1, cleansession, TLS, Websockets, etc.
• Pre-configured Subscriptions, Publications, and Filters (stored for later use)
• Ad-hoc and pre-configured PUBs
• PUB payload can contain %t and %c, replaced by timestamp and clientID respectively
• Support for viewing UTF-8 printable, binary and JSON payloads
• Panel scrolling incoming sub's, latest on top, color-coded topics according to SUBs
• Panel toggable to 'Topic'-mode. In this, incoming msgs do NOT scroll. Instead, last msg overwrites prev on a per/topic basis. Think: temp/outdoors and webserv/status where I see last value without panel scrolling moving: just values on topics change.
• Panel showing low-level communication with broker
• Panels can be frozen (halts all display activity) for, say, taking screenshots
• Screen does not time-out
