B4R Question speed of Bluetooth connection variants

[peacemaker]

HI, All

I have compared the speed of BT connections, BLE and classic BT SPP: https://www.b4x.com/android/forum/threads/resp32simpleble-esp32-ble.93287/post-945116

Do we have any possibility to setup the data transfer speed of BT connections ?

Spoiler: possible overload

Sometimes controller gives such error:

[ 70436][E][BluetoothSerial.cpp:342] esp_spp_cb(): RX Full! Discarding 100 bytes

upd: if 35 msec sending timer - it's OK without this buffer overload error, and speed is 0.98 KBps.
