Hello everyone,
-
i use B-L072Z-LRWAN1 with " I-CUBE-LRWAN" software.
-
when i use the “AT slave exemple”, i can receive the right data from my nod to my php page that decode the JSON array and then i use this function to decode the base64 :
$payload = file_get_contents(‘php://input’);
$var = json_decode($payload,true);
.
.
.
$data64 = $var[‘data’];
$data = base64_decode($data64); // decode functionBut when i use the " End_Node exemple " , i can’t decode the data with my php function that i had present, i have this result :
I noticed that in the" end-node program" there is a function that does this before sending the data :
temperature = 20; /* in °C * 100 /
pressure = 30; / in hPa / 10 /
humidity = 40; / in %*10 */
uint32_t i = 0;
AppData.Buff[i++] = AppLedStateOn;
AppData.Buff[i++] = ( pressure >> 8 ) & 0xFF;
AppData.Buff[i++] = pressure & 0xFF;
AppData.Buff[i++] = ( temperature >> 8 ) & 0xFF;
AppData.Buff[i++] = temperature & 0xFF;
AppData.Buff[i++] = ( humidity >> 8 ) & 0xFF;
AppData.Buff[i++] = humidity & 0xFF;
AppData.BuffSize = i;
LORA_send( &AppData, LORAWAN_DEFAULT_CONFIRM_MSG_STATE);
I have read all the other topic on the forum, but I have not found an answer to my need, please help me, thanks.
