Below is the pin connection chart for Esp32 and esp32c6.
The gpio pins for hci example are configurable through idf.py menuconfig -> Component config -> Bluetooth -> Controller Options -> HCI Config
Below is the pin connection chart for Esp32(Running host) and esp32c6(Running controller).
| Esp32 (Signal) | Esp32 (GPIO Pin) | C6 (Signal) | C6 (GPIO Pin) |
|----------------|-------------------|-------------|---------------|
| Rx | 5 | Tx | 5 |
| Tx | 4 | Rx | 12 |
The same pin configuration could be used for esp32c3, esp32s3, esp32c2 and esp32c6.
For esp32p4 use the following configuration.
| P4 (Signal) | P4 (GPIO Pin) | C6 (Signal) | C6 (GPIO Pin) |
|----------------|-------------------|-------------|---------------|
| Rx | 22 | Tx | 5 |
| Tx | 21 | Rx | 12 |
