peacemaker Expert Licensed User Longtime User Jul 21, 2023 #1 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 Click to expand... upd: if 35 msec sending timer - it's OK without this buffer overload error, and speed is 0.98 KBps. Last edited: Jul 21, 2023
