@A.SochaHi!

 

Sir, as well you always ignore my requests and bugs.

Can you ignore another one, if possible,

now I am trying to send pair command to my broadlink

 

Please login or register to see this code.

 

and this packet fly away to default for HC3 network - 192.168.1.0 / 24

but I want to route this packet to another HC3 interface with address 192.168.10.100

 

so, i can propose to add to constructor parameter "ip"

 

local udp =

    net.UDPSocket(

    {

        ip = "192.168.10.100" --  sock:setsockname(self.opts.ip or HC3.getIPaddress(), 0)
,        timeout = 5000,

        broadcast = true

    }

)

 

 

and this fix issues with multiple network interfaces and UDP packets distribution.

 

thank you very much.

I haven't dealt with it yet, but is it necessary to use broadcast transmission at Broadlink?
I also haven't solved UDP on HC3 yet, but I know that there is a possibility to turn off broadcast parameters
broadcast = false.
I think he will then accept the destination ip.

For the case with broadcast = true, I would rather appreciate the addition of the parameter of the used eth / wifi interface, or use as the parameter designation network (192.168.10.0).
It's hard to say what a bug is and what a property is. Probably ... it's a feature until it is removed as a bug in the next release.

ok! i can trying today test id BL can accept direct packet. on another hand how HC3 send packet... I am not sure what if i send packed to 192.168.10.1 HC3 what has def GW is 192.168.1.1 not trying to send this packet via this IF instead of IF 192.168.10.0

@Martin_Nthank you so much!

it works

 

local UDP_IP_PORT = 80

local MY_IP = "192.168.10.100"

local BROADCAST_IP = "192.168.10.1"

 

package.path = package.path .. ";./TEST/libs/?.lua";

package.cpath = package.cpath .. ";./TEST/libs/?.dll";

local socket = require("socket")

 

local udp = socket.udp()

udp:settimeout(1)

-- udp:setsockname(MY_IP, 0)

-- udp:setoption("broadcast", true)

local resultTX, errorMsg = udp:sendto(txMsg, BROADCAST_IP, UDP_IP_PORT)

print(resultTX, errorMsg)

local rxMsg, ipOrErrorMsg = udp:receivefrom()

print(rxMsg, ipOrErrorMsg)

udp:close()

now i am trying to implemant thsi in HC3

YAY!

i can pair broadlink devices via HC3!

Hurraaaa ... congratulations.
You work nicely on Broadlink ... I'm also planning an acquisition.
