BLE connection error "Device profile has changed. Clear existing ble object with address Exxxxxxxxxxx and recreate it."

Hello,

I am trying to Adafruit Bluefruit BLE device in MATLAB 2019b. Sometimes it gets connected properly and other times it gives the following error: "Device profile has changed. Clear existing ble object with address Exxxxxxxxxxx and recreate it." The connection is setup to allowing reading and writing data from the BLE. However, if I disable the read operation, then it works properly without throwing any error. What causes this error and how can I avoid it? I am attaching my script for setting up the BLE connection. I will truly appreciate any help that you can offer. Thanks

Code -

disp("Initializing BLE connection....");

bleobj = ble("E3C0DB5D3653");

wch = characteristic(bleobj,"6E400001-B5A3-F393-E0A9-E50E24DCCA9E","6E400002-B5A3-F393-E0A9-E50E24DCCA9E");

rch = characteristic(bleobj,"6E400001-B5A3-F393-E0A9-E50E24DCCA9E","6E400003-B5A3-F393-E0A9-E50E24DCCA9E");

subscribe(rch);

write(wch, sprintf('%s', "Hello BLE World","uint8");

MsgRecvd = char(read(rch));
