B4R Question How do I use the esp8266's own serial port

[Cesar_Morisco]

Hey guys
How do I use the esp8266's own serial port to control the hc 12 module with a rate of 9600
I've already looked at some examples and it doesn't work, could anyone give me an example, thanks.

You should use rSoftwareSerial with two GPIOs.

hello thanks for the answer
And this way?

Sub Process_Globals
Public Serial1 As Serial
Public SerialCom  As SoftwareSerial
Public AstreamCom As AsyncStreams

Public SerialCom2  As SoftwareSerial
Public AstreamCom2 As AsyncStreams

Private Rx1 As  UInt = 03
Private Tx1 As  UInt = 01
Private Rx2 As  UInt = 00
Private Tx2 As  UInt = 02
End Sub

Private Sub AppStart
Serial1.Initialize(2400)
Log("AppStart")
SerialCom.Initialize(2400,Tx1,Rx1)'Saida serial
AstreamCom.Initialize(SerialCom.Stream, "astreamCom1_NewData", Null)

SerialCom.Initialize(2400,Tx2,Rx2)'Saida serial
AstreamCom.Initialize(SerialCom.Stream, "astreamCom2_NewData", Null)
End Sub

Sub AstreamCom1_NewData (Buffer() As Byte)
Log("Received: ", Buffer)
End Sub

Sub AstreamCom2_NewData (Buffer() As Byte)
Log("Received: ", Buffer)
End Sub

Sub AStream_Error
    'Log("Erro na comunicação com HC-12")
End Sub

No.

1. Example of rSoftwareSerial: https://www.b4x.com/android/forum/t...s-with-rsoftwareserial-library.65779/#content
Both SerialCom and AstreamCom should be initialized once.

2. You should use two pins that aren't used for anything else. Try pins 10 and 11.

Hello Erel
Thanks for the answer, it worked here
Now I can communicate via serial port with my second control board I only need one pin for this I use GPIO 00 said data works fine.
heartfelt thanks
