LoPy BLE tx/rx max payload size (20 bytes ?)

[queifaro]

Hello,

reading that post https://forum.pycom.io/topic/2306/lopy-bluetooth-characteristic-buffer-size
seems that the maximum ble payload size for rx and tx is 20 bytes only.
Also seems that no MTU negoziation and Long attribute usage are supported.
If it is yet unsupported where that limit resides ? esp-idf-pycom fork,pycom-micropython sw or esp-idf standard sw ?
Is a roadmap already defined (time frame) in order to add support form more than 20 bytes ?

Thanks
