Hi @njh

congrats for the project!!

What is the current status of supporting QOS1 and QOS2 ? I would love to use your gem, but i definitely need these qos.. maybe I can help to develop it..

Best regards

[mishaker]

Hi, I have a plan to develop for MQTT ruby with QoS2.
I need storage for saving received message for QoS2, so I will use redis.

Is there another storage / KVS dbs?

[njh]

Yes, support for persistence is a pre-requisite for QoS 1/2 in my opinion.

Please use a common Ruby API that would allow support for:

• in memory
• flat file on disk
• Redis
• memcache
• database (MySQL?)

I am sure something must already exist.

@njh
ok, I make with in memory cache as default, after that I will make for another storage like "ruby-mqtt-memcache".

[njh]

I have created issue #52 for persistence.

@yuuna , have you any success with QoS 1 and QoS 2?

[Vincent14]

Is there any news or workaround to do QoS 1 please? =)

[njh]

There is some support for QoS 1:

• cdb6280: Send PUBACK when receiving a publish with qos > 0
• 1acc445: Ack after handling qos > 0 packets
• 6b33690: Added puback handling for qos level 1 and 2

I haven't closed this issue because I haven't verified that support is complete.

Any update on this, i.e. is QoS 1 officially supported?
