Code for remote control with WiFi of ADUPAD applications
- wifi_read() function
1. Protocol header definition
Define the headers for WiFi in the Arduino sketch according to the protocol header settings in the ADUPAD app.
#define pinHD F("%%F0")
#define joyHD F("%%F3")
#define strHD F("%%F4")
#define footHD F("%%F1")
#define echoHD F("%%E1")
#define connectHD F("%%F8")
#define optionHD F("%%F9")
#define checkHD F("%%F5")
#define HDLen 4
#define addHD F("%%")
#define addHDLen 2
2. Code to check the connection attempt of ADUPAD app
bool appConnection = false;
if (appConnection) { // If app connection is confirmed
// Execute code after app connection is confirmed
} else { // Before app connection check
if (income_wifi == checkHD) { // Check if the value is %%F5 and set the initial settings
appConnection = true; http_response(); // Confirm the connection of ADUPAD
if (connectionId != 48) { // Initialize ESP01 connection ID when connecting for the first time
while (connectionId != 48) {
connectionId--;
String command = F("AT+CIPCLOSE=");
command += String(connectionId-48);
command += F("\r\n");
esp01.print(command);
delay(1);
}
}
}
}
3. Handling of values according to connection header "connectHD(%%F8)"
%%F8 + connect: Transmit the necessary app settings and current Arduino state values through the iniSet() and sendState() functions
%%F8 + disconnect: Disconnect and change value of appConnection to false
%%F8 + WiFi: change WiFi setting values
if (income_wifi == F("connect")) iniSet();
else if (income_wifi == F("disconnect")) appConnection = false;
else if (income_wifi.startsWith(F("WiFi"))) {
sendMessage(F("This funtion is not available."));
} else Serial.println(income_wifi);
4. Handling of values according to option header "optionHD(%%F9)"
void CheckF9(String temp) {
Serial.println(temp);
if (temp.startsWith(F("RAD"))) { } // if it starts with "RAD"
else if (temp.startsWith(F("CKB"))) { } // if it starts with "CKB"
else if (temp.startsWith(F("CHD"))) { } // if it starts with "CHD"
else if (temp.startsWith(F("LSD"))) { } // if it starts with "LSD"
else if (temp.startsWith(F("STR"))) { } // if it starts with "STR"
}
5. Handling of values according to button header "pinHD(%%F0)"
// income_wifi: %%F0 + Value + %%F1
while(income_wifi.indexOf(pinHD) != -1) { // need while function depend on left arrow pad mode
income_wifi.remove(0, 4); // remove %%F0
ed = income_wifi.indexOf(footHD); // check the index number where footHD(%%F1)
if (ed != -1) { // if the index number is found in the value
temp = income_wifi.substring(0, ed); //Extract data up to index number
uint8_t value = temp.toInt(); // convert to numeric value
income_wifi.remove(0, ed+4); // remove got data
pin_control(value); // execute the code corresponding to the value
} else break; // exit while loop if there's no %%F0
}
6. Handling of values according to SeekBar(slide bar) header "pwmHD(%%F3)"
// income_wifi: id + Count + %% + Heading + %% + Strength + %%F1 (with protocol header %%F3 removed)
temp = income_wifi.substring(0, 1);
uint8_t id = temp.toInt(); // id: 0 or 1 or 2
income_wifi.remove(0, 1); // remove id
ed = income_wifi.indexOf(addHD); // index for %%
temp = income_wifi.substring(0, ed); // extract count
uint16_t count = temp.toInt(); // convert to numeric value
bool ok = true;
if (id == 0) { // 0: left Joystic
if (count == 0) leftCount = 0; // reset leftCount
if (count < leftCount) ok = false; // Skip if the count is less than the stored leftCount
else leftCount = count; // update leftCount
} else if (id == 1) { // 1: right Joystic
if (count == 0) rightCount = 0; // reset rightCount
if (count < rightCount) ok = false; // Skip if the count is less than the stored rightCount
else rightCount = count; // update leftCount
} else { // 2: gravity sensor
if (count == 0) centerCount = 0; // reset centerCount
if (count < centerCount) ok = false;// Skip if the count is less than the stored centerCount
else centerCount = count; // update leftCount
}
if (ok) { // if count validation is OK
income_wifi.remove(0, ed+addHDLen); // remove %%
ed = income_wifi.indexOf(addHD); // index for %%
temp = income_wifi.substring(0, ed);// extract heading
uint16_t heading = temp.toInt(); // convert to numeric value
income_wifi.remove(0, ed+addHDLen); // remove %%
ed = income_wifi.indexOf(addHD); // index for %%
temp = income_wifi.substring(0, ed);// extract strength
uint8_t strength = temp.toInt(); // convert to numeric value
income_wifi.remove(0, ed); // remove value for strength
if (income_wifi == footHD) { // if the value left is %%F1
joystick_control(id, heading, strength); // execute the code corresponding to the value
}
}
Protocol function to send data from Arduino to app
1. Change the state of the button.
void sendPinState(uint8_t pin_val){
Data += pinHD;
Data += pin_val;
Data += footHD;
Data += '\n';
}
2. Transmits an echo for the received value of the button.
void sendPinEcho(uint8_t pin_val){
Data += pinHD;
Data += pin_val;
Data += echoHD;
Data += '\n';
}
3. Change the Joystick state of the app.
// id 0:Left Joystick, 1:Right Joystick 2:Gravity Sensor(change only text)
void sendJoyState(uint8_t id, uint16_t heading, uint8_t strength) {
Data += joyHD;
Data += id;
Data += addHD;
Data += heading;
Data += addHD;
Data += strength;
Data += footHD;
Data += '\n';
}
4. Transmits the echo for the received value of the Joystick.
// SEND JOYSTIC ECHO - ESP01: USE AT PASSIVE JOYSTIC MODE
void sendJoyEcho(uint8_t id, uint16_t heading, uint8_t strength) {
Data += joyHD;
Data += id;
Data += addHD;
Data += heading;
Data += addHD;
Data += strength;
Data += echoHD;
Data += '\n';
}
5. Send text.
void sendText(String text) {
Data += strHD;
Data += text;
Data += footHD;
Data += '\n';
}
6. Instruct the app to click the Disconnect Button.
void sendDisconnect(){
Data += connectHD;
Data += F("DIS");
Data += '\n';
}
7. Use when you want to acquire control authority by using the ACCESS POINT password of the module in the internal network connection through the router. (without using HTML web login)
It can be changed to any name through definition of the passName and passNameLen for processing the password in the sketch and the app send datas starting with passName as password value. This is to enhance security.
#define passName F("PAS:")
#define passNameLen 4
void requestPass(bool val){
Data += connectHD;
Data += val;
Data += passName;
Data += '\n';
}
8. If control authority is given through password confirmation, a cookie value is created and transmitted so that control authority for the data transmitted thereafter can be confirmed.
#define cooLength 5
String cooValue = "u7Dv0";
String makeCooValue() {
cooValue = "";
uint8_t temp = 0;
for (int i = 0; i < cooLength; i++) {
temp = random(39, 123); //random(39, 123); // 39 ~ 122 pick
if (temp == 47 || temp == 59 || temp == 60 || temp == 62 || temp == 92 || temp == 94 || temp == 96) temp = 79;
cooValue += char(temp);
}
return cooValue;
}
void responsePass(bool val){
Data += connectHD;
Data += F("RES:");
if (val) Data += makeCooValue();
else Data += val;
Data += '\n';
}
9. Sends information about the current Wi-Fi connection so that the user can view and edit information in the app about the Wi-Fi connection.
void sendWifiInfo(){
Data += connectHD;
Data += F("INF:");
Data += ssidAP;
Data += ',';
Data += passAP;
Data += ',';
Data += ap;
Data += ',';

Data += ',';
Data += pass;
Data += ',';
Data += ip;
Data += '\n';
}
10. Outputs the message in the form of a pop-up.
void sendMessage(String str){
Data += connectHD;
Data += F("MES:");
Data += str;
Data += '\n';
}
11. Disable the feature, which is default setting, of automatically resend the value When a button or Joystick or Gravity Sensor is changed in the app and then if a response failure error occurs.
It is used when the Arduino intentionally does not respond due to the delay that occurs when sending data using the AT command to the ESP01.
void responseFailResend(bool val) {
Data += connectHD;
Data += F("RFR:");
Data += val;
Data += '\n';
}
12. Set the function to continuously transmit the changed value of the Joystick according to the specified interval.
*** The Gravity Sensor always works in an active Mode.
true: Active Joystick Mode
false: Passive Joystick Mode (transmits only values when the slide bar is touched up)
void setActiveJoystick(bool val){
Data += optionHD;
Data += F("ACT:");
Data += val;
Data += '\n';
}
13. Set transmission interval of ACTIVE JOYSTIC MODE. (Unit: Millisecond)
void setJoystickInterval(uint16_t val){
Data += optionHD;
Data += F("JSI:");
Data += val;
Data += '\n';
}
14. Set the range where the strength of the joystick becomes 0. (enter a value from 0 to 35)
void setJoyZeroRange(uint8_t val){
if (val > 35) val = 35;
Data += optionHD;
Data += F("JZR:");
Data += val;
Data += '\n';
}
15. Set whether or not to use a function that converts the Strength value of Joystick or Gravity Sensor into a value between 0 and 10.
void setJoyStrengthAdjust(bool val){
Data += optionHD;
Data += F("ADJ:");
Data += val;
Data += '\n';
}
16. Activate a timer that sends checkHD(%%F5) at regular time intervals.
Regardless of the app, it is used to reflect independently changed values in the Arduino to the app.
void setRequest(bool val){
Data += optionHD;
Data += F("REQ:");
Data += val;
Data += '\n';
}
17. Set the operation interval of the timer sending checkHD(%%F5). (Unit: Millisecond)
void setRequestInterval(uint16_t val){
Data += optionHD;
Data += F("INT:");
Data += val;
Data += '\n';
}
18. Set the group for the left arrow keypad.

if (val > 2) val = 2;
Data += optionHD;
Data += F("DAB:");
Data += val;
Data += '\n';
}
21. Set the operation function when clicking the label displaying the current connection status.
0: No function.
1: Show only connection information when it clicked.
2: Show connection information and password when it clicked so that the connection and password can be set.
// 0: not use, 1: show only name, 2: show name & pass, defalult: 2
void setSSIDLabelMode(uint8_t val) {
Data += optionHD;
Data += F("SLM:");
Data += val;
Data += '\n';
}
22. Set the activation interval of the gravity sensor and transmission of the tilt value.
// defalt interval : 180 millis, 180, 180 * 6 = 1080
void useGravityAndInterval(uint16_t val){
Data += optionHD;
Data += F("UGI:");
Data += val;

Data += F("LTG:");
Data += str;
Data += '\n';
}
25. Set the toggle/push properties of the right 4 buttons.
// F("0000") // right pad: top-left-right-bottom
void setRightPadToggle(String str){

Data += '\n';
}
26. Set the toggle/push properties of the middle 12 buttons.

void setButtonToggle(String str){
Data += optionHD;
Data += F("BTG:");
Data += str;
Data += '\n';
}
27. Dialog Message: radio button
// option = "A,B,C" -> selection index = 1(A) ~ 3(C)
void dialogRadio(uint8_t id, String title, String option, uint8_t selection){
