BLE shield questions

I am able to send data to the app and read it, but when I try to send a hex value to the shield and view it in the serial monitor it shows up as strange characters.

I am using the software serial. Like I said, the shield seems to send the data fine, but I am having trouble reading it.

Also, how do you clear the buffer on the shield?

Thank you,

the strange characters on the console while sending HEX values is correct.
They are interpreted as string, which then might include charactes others than [a-z0-9].

What if you send real strings over the SoftwareSerial? Is the Baudrate matching 19200 ?
Try to send ff to the buffer clear characteristic to reset the buffer.

The Sample code in the Github repository does this by pressing a button. You should be able to achieve that easily.
