Bluno Beetle V1.1 - receiving garbled characters through Bluetooth in BlunoBasicDemo

I just got Bluno Beetle V1.1 and I am trying to make it talk via Bluetooth to Android. I can connect but when I Send Data "123" I get back garbled characters (not random), why? Is it some encoding problem? How do I fix that?
Code: Select all
I/System.out: onCharacteristicWrite success:12345 I/System.out: onCharacteristicChanged 022&�

When I connect to the device in Serial Monitor, there are no issues (sending 123 gives me back newline separated numbers)

My environment:

On Bluno I run - from Ubuntu snap install of the IDE (snap install arduino-mhall119 --classic):
Code: Select all
void setup() { Serial.begin(115200); //initialize the Serial } void loop() { if(Serial.available()) { Serial.write(Serial.read()); //send what has been received Serial.println(); } }

I built BlunoBasicDemo with only one change compileSDK 27 and buildToolsVersion "26.0.3". Android log is:
