hello, good day, I am making an example with a 5500 chip in esp32 with the socketioclient library, but when I want to send the json to my server, they are only left on the waiting list and I don't know what is happening to me, before all this an error message about invalid mbox appeared and I added the following line of code esp_netif_init(); and it was fixed, but once entering the loop the following happens:

If someone could help me, it would be very helpful. Thank you. I'm new to ethernet connectivity. I hope you understand.
I am trying to communicate to a KASA HS103 smart plug using an HTTPS POST request sent via ESP32 (LoRa V2). For the actual POST content, I'm quite new to HTTP and have been following the instructions here: https://itnerd.space/2017/01/22/how-to-control-your-tp-link-hs100-smartplug-from-internet/
This is the POST request I am trying to send (with token & IDs modified):
URL: https://use1-wap.tplinkcloud.com/?token=fb2f7209-ATebDhHDOxB2wWc6wslPewO&appName=Kasa_Android&termID=1263f577-4387-4d3e-be79-705445d33bb08&appVer=1.4.4.607&ospf=Android+6.0.1&netType=wifi&locale=en_US
{
"method":"passthrough",
"params":{
"deviceId":"80068FEB5A735A5BB187B4EC309EF1BE1D6D8997",
"requestData":"{\"system\":{\"set_relay_state\":{\"state\":1}}}"
}
}
This will turn on the smart plug. I have verified that the POST request itself works, with both an online API tester (https://reqbin.com/) and through cURL on my MacBook.
I retrieved the URL token and device ID by authenticating with TP-Link server using my credentials through the API tester (also in the instructions linked above).
However, I am unable to control the smart plug when sending with ESP32. I am writing and compiling through the Arduino IDE, using the Heltec framework / libraries. Here is my code (started with the code from Rui Santos here and modified for my application):

Here is the output from the serial terminal:
Connected to WiFi network with IP Address: 192.168.X.XXX
Timer set to 5 seconds (timerDelay variable), it will take 5 seconds before publishing the first reading.
Client Created!
HTTP Response code: 200
HTTP String: {"error_code":-10100,"msg":"JSON format error"}
The smart plug does not turn off when uploading and running on ESP32.
Doing a quick search online for POST response codes, receiving 200 seems to mean the request was processed and OK, yet the error code is negative and message is "JSON format error".
Any ideas why this POST request is not working? Or anything I should try to get more info?
Thanks in advance!
Digging into "JSON format error" - turns out I had an extra "" around the 'requestData' value which parsed fine in cURL but could not be understood when sending raw through ESP32.
Removing those quotes fixed the problem and now I'm able to send POST requests successfully.

At the moment I try to send packets between one Heltec WIFI LoRa V2 and another by reading the serial-line and sending the input via LoRa.
Small packets (like 30 bytes) work every time, but as bigger the packet gets the packet won't be received every time or even never.
So I write a little sending loop, where my sender sends at every iteration a packet, which gets every time 10 byte bigger, and surprisingly every packet was received by the sender (I tried that until 500 bytes).
After that, I wanted to send a 80 byte serial input message and this did not work. Do you know what's the problem with that?
void setup() {
// ... LoRa.begin(); ....
LoRa.onReceive(onReceive);
// ... LoRa.receive(); ...
}
void onReceive(int packetSize) { // uses the interrupt pin on the dio0
String packet = "";
packSize = String(packetSize,DEC);
for (int i = 0; i < packetSize; i++) {
packet += (char) LoRa.read();
}
Serial.println(packet);
delay(5);
} ```
``` // writer
boolean sendPacket (String packet) {
Serial.println("Send begin");
LoRa.beginPacket(false); // true: optional implicit mode (--> Set everything on both sides?!)
LoRa.setTxPower(14,RF_PACONFIG_PASELECT_PABOOST);
LoRa.print(packet); // also LoRa.write(byte(, length));
LoRa.endPacket(false); // true: async mode: doas not wair until transmission is completed
delay(250);
// put the radio into receive mode
LoRa.receive(); // set redio back in receive mode
delay(750);
Serial.println("Send end");
return true; // will be changed
}
void loop(){
while(Serial.available() > 0 ){
delay(2); //delay to allow byte to arrive in input buffer
String text = Serial.readString();
digitalWrite(LED, HIGH); // turn the LED on (HIGH is the voltage level)
boolean packetSent = false;
while (!packetSent) {
packetSent = sendPacket(text);
if (packetSent) {
Serial.print("Packet has been sent: ");
Serial.println(text);
} else {
Serial.print("Retry sending packet: ");
Serial.println(text);
}
}
digitalWrite(LED, LOW); // turn the LED off (HIGH is the voltage level)
}
} ```
Basically, my project uses a force-sensing resistor to detect occupancy on the chair. The ESP8266 WiFi would wake from the sleep mode and send an update to the server. If there is no occupancy, the ESP8266 goes back to sleep.
My project uses Wiolink, a dev board that uses a ESP8266 WiFi chip. Hence, it is quite impossible to connect GPIO 16 to RST to wake up ( or reset ) the device.
Deep sleep is predefined at a set amount of time using this function ESP.deepsleep(). Is it possible to wake up with an external interrupt such as the force sensing resistor?
String apiKey = ""; // const char* ssid = ""; // wifi username const
