6. BLE evaluation
ESP32-C3 supports BLE 5.0
Next, I will use the BLE 5.0 routines and mobile phone APP to simply test BLE.
Here I use the ble_spp_server routine to test, and the APP uses nRF Connent t...
I have compiled a NDIS filter for VISTA. Now it cannot be loaded with osrloader. The error is "the device connected to the system is not functioning". I tried compiling the filter that comes with WDK6...
