Dear STMicroelectronics Support Team,
I have built a custom wireless charger based on the STEVAL-WBC2TX50 evaluation board, following the provided BOM and schematics.
I successfully flashed the STSW-WBC2FW_V1300 firmware into the STWBC2-HP controller chip and connected to the STSW-WBC2STUDIO GUI to monitor system behavior.
I understand that Qi 1.3 devices will not charge due to authentication requirements. However, I would like to confirm whether I should be able to charge Qi 1.2 and older devices (e.g., iPhone 11) since they do not require authentication. If I should be able the charge Qi1.2 devices, this suggests an underlying hardware issue in my design.
Currently, the GUI event window continuously shows "ping_timeout" errors, as seen in the attached screenshot.
Could you please provide guidance on potential causes and troubleshooting steps to resolve this issue?
Thank you for your support.
