According to the ESP8266 Datasheet, the RAM available to the programs is 
around 50kB..   The next Question is does the ESP8266 support Flow Control?

On the Bluetooth portion???

According to the ESP32 Datasheet, the Bluetooth is Class 1-3, and the 
Stack meets Bluetooth v4.2 BR / EDR and BLE specification.
