Testing Compile Lambda

It expects the following payload:

{
  "sketch": string,
  "robotId": string,
  "clientConnectionId": string,
  "robotConnectionId": string
}

One could use the following blink sketch:

#include <Arduino.h>\n#include \"src/LeaphyEspOta.h\"\n\nLeaphyEspOta Leaphy;\n\nint ledState = LOW;\nconst long blinkWaitInterval = 500;\n\nvoid setup() {\n Leaphy.setupOta();\n pinMode(LED_BUILTIN, OUTPUT);\n}\n\nvoid loop() {\n Leaphy.handleLoop();\n digitalWrite(LED_BUILTIN, LOW);\n delay(blinkWaitInterval);\n digitalWrite(LED_BUILTIN, HIGH);\n delay(blinkWaitInterval);\n}\n

Same sketch pretty-printed:

#include <Arduino.h>
#include "src/LeaphyEspOta.h"

LeaphyEspOta Leaphy;

int ledState = LOW;
const long blinkWaitInterval = 500;

void setup() {
  Leaphy.setupOta();
  pinMode(LED_BUILTIN, OUTPUT);
}


void loop() {
  Leaphy.handleLoop();

  digitalWrite(LED_BUILTIN, LOW);
  delay(blinkWaitInterval);
  digitalWrite(LED_BUILTIN, HIGH);
  delay(blinkWaitInterval);
}
