Decoding JSON received with Serial

[marlonrettore]

Good morning mate,

I'm getting a JSOn via Serial from another arduino, how do I do the decoding of this JSON, I could not do it. Could you give me an example of a serial JSON reception of his decoding?

Thanks, I'm waiting

Hello @marlonrettore,

It's a bug.
I'm calling Stream.read() which doesn't take the timeout into account.

Thanks for reporting this.

Regards,
Benoit

Good morning mate

Would it look like this?

char json[] = Stream.read();

StaticJsonBuffer<200> jsonBuffer;

JsonObject& root = jsonBuffer.parseObject(json);

if (!root.success())
{
Serial.println("parseObject() failed");
return;
}
const char* sensor = root["sensor"];
long time = root["time"];
double latitude = root["data"][0];
double longitude = root["data"][1];

Hello @marlonrettore,

I'll be even simpler, as no char[] is required:

JsonObject& root = jsonBuffer.parseObject(Serial);

But you'll need a bigger JsonBuffer to hold the copy of the input.

It's already fixed in the issue422 branch if you want to try.
