Android Question MqttClient - send info to clients no using B4X

[mmanso]

Hi All,

When we use the MqttClient in B4A it expects us to send Bytes(). We "feed" it with something like:

serializator.ConvertObjectToBytes(var)

How do you deal with other clients that are connected to the same mqtt broker? It's possible o send JSON or something between clients?

Thanks.

Create a json and send this. Other clients (others than B4X) are not able to read or send serialized content.

dim json as String
' fill json with the jsondata
mqtt.send(json.GetBytes("UTF8")) ' Or whatever commands you need to use.

Thanks! I'll try it out.
