Cannot send data from iPhone app to arduino using HM10

Here is the code I'm using from Martyn Currey for my HM10 module:

#include <AltSoftSerial.h>
AltSoftSerial BTserial;
// AltSoftSerial Library, for an extra serial port

char c=' ';
boolean NL = true;

void setup()
{
Serial.begin(9600);
Serial.print("Sketch: "); Serial.println(FILE);
Serial.print("Uploaded: "); Serial.println(DATE);
Serial.println(" ");

BTserial.begin(9600);
Serial.println("BTserial started at 9600");
}

void loop()
{
// Read from the Bluetooth module and send to the Arduino Serial Monitor
if (BTserial.available())
{
c = BTserial.read();
Serial.write(c);
}

// Read from the Serial Monitor and send to the Bluetooth module
if (Serial.available())
{
c = Serial.read();

// do not send line end characters to the HM-10
if (c!=10 & c!=13 )
{
BTserial.write(c);
}

// Echo the user input to the main window.
// If there is a new line print the ">" character.
if (NL) { Serial.print("\r\n>"); NL = false; }
Serial.write(c);
if (c==10) { NL = true; }
}
}

I am able to successfully type something in the serial monitor and receive it on my iPhone using the BLExAR app. But when I send anything from that app to the HM-10 the serial monitor doesn't display anything. I think it is because the BTSerial.available always returns 0, though I'm not sure why that is. To try to get more information, I used the iPhone BLE Scanner app's Custom Service to write to the module. Upon doing that, I noticed that it will not actually read the value until I then manually read the value from the app. Even after reading the value though it only displays "No value. Value - String at .

Looking for any suggestions since googling isn't helping much and I am very new to the BLE stuff.

If the BT unit is not actually sending anything to the Arduino, the Arduino doesn't have anything to do with your issue. Can you show that the BT-unit sends serial data.

Where would I look to see if the BLE sends serial data? (Sorry - again I’m new to all of this). I’m assuming it does since it can get data from the serial monitor and send it to the iPhone app

check my response in the 'other thread' (why did you start a new one ?? )
