Hi I need some hep with the HTTP integration , I have followed the youtube video. i have also read most of the posts of the http integrations . there is a lot of discussion around REST and MQTT as a use to collect the data from the TTN publish. However i woul d need to keep it a bit simpler due to…

You are doing a json_decode and then saving, and as text, which is not appropriate because $ttndtajs is no more text but an object. You can use var_export() to obtain a parsable serialization of that object, however is is like saving JSON directly. When I started using TTN, I used this small PHP sc…

Hi, Thank you very much for the explanation, I made the changes as suggested and now it is publishing the data as expected. Major thanks to Arjan for fixing my gramer in the code block. could not find a button in the message box to do it correctly Regards

And yes, this script is totally missing input sanitization, source verification etc: it is ok just to check functioning. Follow Arjan link for some explanation.

Hi Udlora Quick question $freq=$data->metadata->frequency; //shows the frequency nicely i would like to read the rssi value as well, but the following is not returning any value. $rrssi=$data->metadata->gateways->rssi; Is there a different way that i should get the data out ? Regards

[image] coetzeec2380: $rrssi=$data->metadata->gateways->rssi; Multiple gateways might have received the device’s transmission, so you’ll get an array in the JSON , each item being the details of one gateway. After parsing JSON into a PHP object, I assume you’ll also get an array. PHP is not my…

Arjan is right, both conceptually and syntactically :slight_smile:. At my very first attempt I assumed I was reaching just one gateway, thus I checked gateways[0] only, but with my surprise sometimes data was received by a 27km far gateway too. Better to look at the whole array…

Hi UdLora, I tried this script: [image] UdLoRa: <?php //Receive from TTN $postdata = file_get_contents('php://input'); file_put_contents('yourfile.txt', $postdata . PHP_EOL, FILE_APPEND); echo 'ok'; ?> However each time I send a (simulated) uplink message through HTTP POS…

Are you only testing with Chrome? That doesn’t make sense; that will create a HTTP GET request, not a HTTP POST. You should configure the URL of your script in the integration. To test without the integration, use something like Postman , which allows you to use POST rather than GET.

I tested with opera as well. Same issue. I will have a look at Postman. [image] arjanvanb: You should configure the URL of your script in the integration. I have simply entered the URL that I want to send to (where index.php is hosted), using the POST method.
