@shrikantlahase, I am not sure if mosquitto could bridge to emqttd. If any issues, please contact us:)

[shrikantlahase]

Hi feng,

1. Bridging mosquitto broker and emqttd broker was not successful. Can you
   do any help...?
2. I am trying to connect paho mqtt client which written in python to
   emqttd broker but its not happening. How to connect as a client to emqttd
   broker...?

Regards & Thanks,
Shrikant

Hi @shrikantlahase

1. Please add my Skype: feng.emqtt.io to discuss the bridge issue.
2. We also use The paho client library written in python to test emqttd broker, so it should work well with emqttd.

Hi feng, I am attaching my python client code. I tried command "./emqttd_ctl clients list" to see clients connected but output is blank. Can u tell me anything wrong in code...? or need to check on broker side Thanks and regards,

[emqplus]

please open the console log in etc/emqttd.config, and then ‘./bin/emqttd console’ to debug:

    {handlers, [
        {lager_console_backend, info},
       ...

bridge from mosquitto to emqttd not successfully. I've test both mqtt broker by mosquitto_pub and both of them works fine.

mosquitto bridge configuration:
connection emqttd
address 101.200.88.13:1883
topic /test both
#bridge_protocol_version mqttv31
start_type automatic
local_clientid C_00:0C:29:2B:77:52

emqttd error log:

@shrikantlahase, @jianglinchun mosquitto bridge works now.

The mosquitto bridge uses a special 0x83 as protocol version in the CONNECT packet.

Please check out the '0.17' branch.

[jianglinchun]

Unexpected behavior. Pls check the following mosquitto log(unacceptable protocol version and works after retry???):

1455734681: Connecting bridge 000C292 (101.200.88.13:1883)

[emqplus]

Please check the console log of emqttd broker, configure etc/emqttd.config:

{lager_console_backend, info},

[emqplus]

@jianglinchun The broker will reply 'unacceptable protocol version' error code when mosquitto bridge CONNECT packet received. I fixed in the latest 0.17 branch, please pull and verify.

[jianglinchun]

Thank you for you fix. It works now.

[emqplus]

I can not make it work:
