"POST" in the Server

[FrancoCapraroArg]

Hi, i have a MDEK using the 1 gateway/1 tag/4 anchors “configuration” and running everything fine.
I want to know if is posible to do a “Post” message (as Thingspeak do) to the server.
Example :

if (cIient.connect(server,80)) {
String postStr = apiKey;
postStr +=“&fieId1-=”;
postStr += String(xc);
postStr +=“&fieId2-=”;
postStr += String(yc);
postStr +=“&fieId3-=”;
postStr += String(zc);
postStr += “\r\n\r\n”;
client.print(“POST /update HTTP/1.1\n”);
client.print(“Host: api.thingspeak.com\n”);
client.print(“Connection: close\n”);
client.print(“X-THlNGSPEAKAPIKEY: “+apiKey+”\n”);
client.print(“Content-Type: application/x-www-form-urlencoded\n”);
client.print(“Content-Length: “);
client.print(postStr.Iength());
client.print(”\n\n”);
client.print(postStr);
Serial.println(“% send to Thingspeak”);
}

Sorry if my question its so obvious.

Hi Franco,

I have no experience with Thinkspeak. In general I think it’s possible to create a POST/MQTT connector but I don’t know which types of request/message it needs so I don’t know if PANS is ready for a such integration.

If you make any progress with Thinkspeak please share with us. It’s an interesting IoT platform.

Thanks,
Cheers, TDK

yes ! im trying to do it, but i need to know how the Gateway sends the data to the server.

If “post” way is used , try to make a post in the server i need the apiKey of the server (this is not the “dwmpass” password showed in the dwn1001/dwm1001.config )

Hi Franco,

when you talk about Server, do you mean the MQTT Broker?
See this post for the details about the data chain:

10 000 m² area to cover with RTLS web manager also

Hi Ahmed, The data chain looks like this: Anchor/Tag – Bridge – Kernel Module – DWM Daemon – DWM Proxy – MQTT Broker – DRTLS Web Manager / MQTT client A simplified data flow of the uplink data (from the Edge node toward the Server) can be like this: The Gateway will collect all the Location and IoT data which it can see from the in-range Anchors and Tags. The data will then be forwarded to the DWM Daemon (which will be one per Gateway, so there will be as many Daemons as DWM1001 modules run…

Here are the list of configuration files:

1. /etc/dwn1001/dwm1001.config contains configuration for the DWM Daemon
2. /etc/dwn1001/dwm1001-proxy.config contains configuration for the DWM Proxy

The Daemon and Proxy connect to the MQTT Broker using these credentials:

proxy_server_host = "localhost"
proxy_server_port = 1885
mqtt_user = "dwmuser"
mqtt_password = "dwmpass"
mqtt_topic_prefix = "dwm"

It is however used only if the MQTT Broker requests them (see /etc/mosquitto/mosquitto.conf). The same credentials have to be used by the Thinkspeak I believe.
