Hello all,

Am trying to implement code to send SMS and make a Call (for testing only) 
using this PIC16F19176 with a GSM module: GA6-B.
Heres the arduino code:

// 
--------------------------------------------------------------------------- 
// Example Support of GOOUUU TECH IOT-GA6-B Gprs Gsm Module 
// 
--------------------------------------------------------------------------- 
#include <SoftwareSerial.h> 
#define GSM_RX 2 // Arduino pin 2 to URX 
#define GSM_TX 3 // Arduino pin 3 to URX 
SoftwareSerial sim(GSM_RX, GSM_TX); // 
// The GSM 
String number = "07905582XXX"; //-> change with your number 
void setup() { 
Serial.begin(9600); // GPS on 0,1 pin 
Serial.println("System Started..."); 
sim.begin(115200); 
delay(1000); 
Serial.println("Communicating GSM/GPS....."); 
sms(); //send sms 
call(); //call to us 
} 
void loop() { 
//do your code 
} //loop 
//-----------GSM Function 
--------------------------------------------------------- 
void sms() 
{ 
Serial.println ("Sending Message"); 
sim.println("AT+CMGF=1"); //Sets the GSM Module in Text Mode 
delay(1000); 
Serial.println ("Set SMS Number"); 
sim.println("AT+CMGS=\"" + number + "\"\r"); //Mobile phone number to send 
message 
delay(1000); 
String SMS = "Sample SMS is sending....."; //sms content 
sim.println(SMS); 
delay(100); 
sim.println((char)26);// ASCII code of CTRL+Z 
delay(1000); 
} 
void call() { 
sim.print (F("ATD")); 
sim.print (number); 
sim.print (F(";\r\n")); 
} 

And here relevant part of my code (not working):
--
include pps
pps_control_lock(FALSE)
RC6PPS = PPS_TX1  -- TX1 re-assigned to C6  (default)
RX1PPS = PPS_RC7  -- C7 re-assigned to RX1  (default)
pps_control_lock(TRUE)
--
--
--
-- ok, now setup serial
--const serial_hw_baudrate = 999_000
-- (115_200 / 256_000 / 512_000 já testados com sucesso)
--
-- Include and initialize serial hardware library.
const serial_hw_baudrate = 115200
--const serial_hw_baudrate = 9600
alias pin_TX_direction is pin_C6_direction  -- Transmit pin.
alias pin_RX_direction is pin_C7_direction  -- Receive pin.
include serial_hardware
serial_hw_init()
--
-- output library
include print
--
include delay
--
const byte AT1[] = "ATD"
const byte AT2[] = "XXXMyNumberXXX"
const byte AT3[] = ";"
--
forever loop
   --
   led = OFF
   delay_1ms(10_000)
   --
   led = ON
   print_string(serial_hw_data,AT1)
   print_string(serial_hw_data,AT2)
   print_string(serial_hw_data,AT3)
   --print_crlf(serial_hw_data)
   delay_1ms(5_000)
   --
end loop

Testing only with a CALL making. No success so far.
AT commands are sent (received and read in computer)
Any help will be great.
Thank you very much.

Best Regards,
Filipe Santos.
