Welcome to the MQTT mailing list and discussion group
MQTT is an OASIS standard, lightweight publish/subscribe messaging protocol, originally developed for sensor applications. MQTT is extremely useful and widely adopted in mobile environments due to the low power consumption, simplicity of API, and small bandwidth used. Clients and servers are available in many different programming languages - visit mqtt.org
for more information about the protocol and the community around it.
This group brings together discussions of the protocol and different implementations. Other discussion media exist (for example, individual software implementations may have their own project resources) but this group is for discussion of the protocol and MQTT ecosystem as a whole. Off-topic debates, discussion around alternative protocols, etc. do not belong in this group. Thank you!
