      - **Solution 1**: For ESP-LyraP-TouchA, do not initialize IO6 (PHOTO) and IO11 (NETWORK). Please note that the six buttons on ESP-LyraT-8311A still cannot be used. **Solution 2**: On your ESP-LyraP-LCD32, remove R39, change R41 to 100 Ohm, switch BLCT_L to on. For your ESP-LyraP-TouchA, do not initialize IO11 (NETWORK). If you want to use the six buttons on your ESP-LyraT-8311A, also do not initialize IO6 (PHOTO).
