- Tue Mar 29, 2016 7:04 am #44241 Hi everyone,

Has something changed recently that broke SSL support in MQTT? I created a new build using the build service yesterday, including SSL support - I wanted to add the CJSON module to my firmware. Anyway, after doing that, my application can't connect using a secure MQTT connection. I get a "ssl not available" error, even though I see evidence that SSL is enabled in the start up message.

Thanks!

Test Program:
================================================================================
MQTT_CLIENT = nil

function mqttConnected(client)
print("mqttConnected(client)")
end

function mqttFailed(client, reason)
print("mqttFailed(client, reason)")
end

function mqttDisconnected(client)
print("mqttDisconnected(client)")
end

function hubAddressReady(sk, ip)
print("hubAddressReady(sk, ip)")
if (ip ~= nil) then
local a = "[STRING-03]"
local b = "[STRING-02]"
local c = "[STRING-03]"

MQTT_CLIENT = mqtt.Client(a, 120, b, c, 1)
MQTT_CLIENT:on("offline", mqttDisconnected)
MQTT_CLIENT:connect(ip, 8883, 1, 1, mqttConnected, mqttFailed)
end
end

function networkOnline()
print("networkOnline()")
net.dns.resolve("[STRING-04]", hubAddressReady)
end

wifi.setmode(wifi.STATION)
wifi.sta.eventMonReg(wifi.STA_GOTIP, networkOnline)
wifi.sta.eventMonStart()
wifi.sta.config("[STRING-05]", "[STRING-06]", 1)

Output:
