Status of Bluetooth for ESP32

I spend lot of days to get Bluetooth up and running in a very first simple step
So is time to give a first status.
To be open, I'm not sure, we will ever get it running in a nice way.
Memory consumption in binary file and in RAM is huuuuge

This is what I did in some short steps:

1. got the example from esp-idf for UART-Server running
   
2. got connected from my mobile, using nRF Toolbox
   
3. rebuilt source and added to Espruino/targets/ESP32
   
4. got huge binary, up to 1400KB
   
5. created a new partition table to support this big application size
   
6. flashed and got "no heap" and reset, reset, ....
   
7. changed config and removed classic Bluetooth and some other memory eater
   
8. tons of problems, sometimes even without any error message
   
9. had to reduce jsvars from 5000 down to 2000 and now its working
   
   

There is still no functionality available in Javascript, and UART is receiving data only.
Question is, should I spend more time on this, or wait for availibility of breadboards with ESP32 wrover which has additional PSRAM.
