Go to sleep after sending data – safeguarding

[Zygfryd]

Hi,

I realised that if you use the commands:

ResponseStatus rs = e220ttl.sendMessage(&struct1, sizeof(struct1));
Serial.print(rs.getResponseDescription()); 

and even if the outcome is “Success” it does NOT mean the message was sent.

The only way to make sure transmission is finished is to observe AUX input – it takes around 360ms and (probably) it depends on the amount of data to be sent:

#define AUX xx
pinMode(AUX,INPUT);
while (digitalRead(AUX) == 0) {}

and once it is LOW, you can safely send E220 to sleep, i.e. this way:

#define M0    19
#define M1    21
pinMode(M0, OUTPUT);
pinMode(M1, OUTPUT);
digitalWrite(M0, 1);
digitalWrite(M1, 1);

Hi Zygfryd,
sorry if I answer only now. Yes, if you set AUX, you get better optimization in terms of time, if you don’t set AUX, I use an arbitrary amount of time that covers the wide case with minimum time, but It can be possible that not all if you have an issue in a particular aspect I advise adding a delay to be sure of the sending.
Bye Renzo
