Hi,
I'm puzzled how message receive happens. I am building a infrared transmitter. I decoded the NEC signals from original remote, they look like this (hex): 0xF7C03F. This is power on command.
Now I want to send those signals over MQTT, which mysgw transfers over NRF24L01+ to arduino. But how to convert messages so that they look alike at both ends? is that number too big to send (3 bytes)?
As I send that exact command from arduino:
#define CMD_ON 0xF7C03F
...
send(msg_ir.set(CMD_ON));
it looks like this on MQTT looking from mosquitto_sub:
MySensorsGW/out/7/1/1/0/32 16236607
When I send that back:
mosquitto_pub -h droidcam.ikenet -p 1883 -t MySensorsGW/in/7/1/1/0/32 -m 16236607
the code:
uint32_t ircode;
ircode = atoi( message.data );
...
Serial.print( "V_IR_SEND data invalid: " );
Serial.print( message.data );
Serial.print( ", ircode: " );
Serial.println( ircode );
prints it out like this:
V_IR_SEND data invalid: 16236607, ircode: 4294950975
the numbers don't match. 16236607 is not the original CMD_ON code.
This is the receive function:
// IR remote command codes

#define CMD_DIMMER 0xF7807F

void receive(const MyMessage &message)
{
uint32_t ircode;
Serial.print( "Received something of type: " );
Serial.println( message.type );
if (message.type == V_IR_SEND) {
Serial.println( "V_IR_SEND command received..." );
ircode = atoi( message.data );
//ircode = message.data;
switch (ircode) {
case CMD_BRIGHTER:
case CMD_DIMMER:
case CMD_OFF:
case CMD_ON:
case CMD_FLASH:
case CMD_STROBE:
case CMD_FADE:
case CMD_SMOOTH:
case CMD_RED:
case CMD_RED1:
case CMD_RED2:
case CMD_RED3:
case CMD_RED4:
case CMD_GREEN:
case CMD_GREEN1:
case CMD_GREEN2:
case CMD_GREEN3:
case CMD_GREEN4:
case CMD_BLUE1:
case CMD_BLUE:
case CMD_BLUE2:
case CMD_BLUE3:
case CMD_BLUE4:
{
Serial.print( "V_IR_SEND code received: ");
Serial.println( message.data );
send_ircode(ircode);
ack_ir_to_controller(ircode);
break;
}
default:
{
Serial.print( "V_IR_SEND data invalid: " );
Serial.print( message.data );
Serial.print( ", ircode: " );
Serial.println( ircode );
return;
}
}
}
for (int i=0; i<5; i++) {
digitalWrite(LED_PIN, HIGH);
wait(100);
digitalWrite(LED_PIN, LOW);
wait(100);
}
}
I suppose it has to do with data length and auto conversion of variables. It perhaps worked if I use smaller numbers to set the IR code value. But however, I'd like to understand how this is supposed to work?
BR,

PS, this is IR controlled LED light bulb from LIDL, and commands do work with the given codes.
