RX HM-10 connected to pin 11 and TX HM-10 to pin 10.
SoftwareSerial BTSerial(11, 10); //RX|TX
The constructor for Software Serial lists the pins in the order as you indicate -- Rx then TX. This is from the point of view of the Arudino.
Your connections are not correct. TX of the HM 10 connects to RX of the Arduino and RX of the HM 10 connects to the TX of the Arduino.
