Hi @betterboards
Thanks for posting on the Infineon Developer community.
1. Does the WLC1115 IC come pre-loaded with default firmware? Is it possible to use the IC in the default configuration (as defined by the reference design) without flashing firmware or configuring the device using a computer?
There is only a bootloader on the WLC1115. When you connect it with the configuration tool then you can observe the bootloader associated with it only .It is necessary to update the firmware to proceed further.you can find the more details about how to configure and download the firmware in section 4.2 of WLC1115 MP-A11 15-W wireless power transmitter (REF_WLC_TX15W_C1) user guide .
2.Can you provide a table describing the different LED states? I have not been able to find this in any of the documentation. I am referring to the red and blue LEDs used in the reference design on pins 26 (LED1) and 27 (LED2)?
The LED 1 will blink five times in Blue and red colour after connecting the USB power adapter to the refrence board's USB type-C socket to indicate that the board is ready for operation.The LED status is displayed below when the receiver is placed on the transmitter interface.
