Massive Bluetooth speed improvements

tried with a PuckJS, uploaded v199 and it fails on connecting via webIDE:

>>> BLE configured. Receiving data...
Connected [object Object]
Received a prompt after sending newline... good!
>>> Sending...
---> "\u0010print(\"<\",\"<<\",JSON.stringify­(process.env),\">>\",\">\")\n"
>>> Sent
WARNING: No result found for "process.env" - just got ""
ERROR: [notify_error] Unable to retrieve board information. Connection Error?
Device found {"portName":"Puck.js cb34"}
[success] Connected to Web Bluetooth, Puck.js cb34 (No response from board)
>>> Connected to Web Bluetooth, Puck.js cb34 (No response from board)

did a hard reset - still nothing :(
