Problemas com SIM800L (ALGUMAS SOLUÇÕES)

Peguei esse sketch para testar o modulo SIM800L, o código está logo abaixo

Estou usando a porta 10 como RX e 11 como TX do SOFTSERIAL
A Porta RX vai na PORTA TX do Módulo
A Porta TX vai na PORTA RX do Módulo

Para testar a conexão HTTP usei os seguintes comandos

AT

AT+SAPBR=3,1,“Contype”,“GPRS”

AT+SAPBR=3,1,“APN”,“zap.vivo.com.br”

AT+SAPBR=1,1

AT+SAPBR=2,1

AT+HTTPINIT

AT+HTTPPARA=“CID”,1

AT+HTTPPARA=“URL”,“http://suv.pres-switch.com.br/add.php?teste1=1;texte2=3

AT+HTTPACTION=0

AT+HTTPTERM

Algo que percebi é que o primeiro comando deve ser o AT, para ele “LIGAR o Módulo”
