Roboremo with Adafruit Feather 34u2 BLE won't display data

Trying to make an ECG heart monitor Using Adafruit Feather 34u2 BLE, a Sparkfun Heartrate monitor module and Samsung Galaxy Note8 running Android 9. The Sparkfun module modulates analog A0 to create the heart rhythm. Roboremo will connect to the BLE on the micro-controller (running Arduino sketch) but will not display data.

- The Adafruit Bluefruit app connects and displays data either in raw form within in the UART module, and it plots the data in the plotter module.

- The data is also displayed properly with the Serial USB terminal emulator app and it's bluetooth companion app that supports BLE both running on my smartphone.

- The data is being sent to the bluetooth modem in the micro-controller and is transmitted to a connected Android device, this is confirmed.

- In Roboremo I've tried connecting manually through the connect menu. In this case, the bluetooth light on the micro-controller turns on indicating a connection. BUT. the Roboremo app locks up on the "waiting" message. I have to close and reopen the app to recover.

- When I create a button called Connect, and hard code the UUIDs in the "when pressed" section, the connection is established but the plot window displays no data.

- The Arduino IDE serial plotter and a Processing sketch in windows also graph properly.

-  Below is the UUIDs I put inside Roboremo connect button. This information is derived from the Adafruit website AND when the BLE module is polled for info from within the Adafruit BlueFruit Android app.

-  Speed in Arduino serial setup is 115200 as is the Roboremo app...  

I've exhausted everything I can think of, even purchased the upgraded Roboremo just in case that would help. It didn't. Any help would be most appreciated.

**** Interface Connect command - No cr/lf in this configuration data within the app. I formatted here to make it easier to read***

********* Adafruit Feather 34u2 microcontroller info *****************

Google Adafruit Feather 34u2 BLE from Adafruit. I just joined the forum and cannot post links yet...

"The Bluefruit LE module is an nRF51822 chipset from Nordic, programmed with multi-function code that can do quite a lot! For most people, they'll be very happy to use the standard Nordic UART RX/TX connection profile."

I'm very impressed with this app! Well worth the $8 to teach grandsons about creating devices instead of being users only...
