Support may be added later, and will use the same SPI interface. While the CYW43439 supports both 802.11 wireless and Bluetooth, initially Pico W does not have Bluetooth support. The CYW43439 wireless chip is connected via SPI to the RP2040. Adding grounded metal to the sides of the antenna can improve the antenna’s bandwidth. For instance, putting metal under or close by the antenna can reduce its performance both in terms of gain and bandwidth. The interface typically runs at 33MHz.įor best wireless performance, the antenna should be in free space. Only when an SPI transaction isn’t in progress is it suitable to check for IRQs. The Infineon CYW43439 DIN/DOUT and IRQ all share one pin on the RP2040.
The CLK is shared with VSYS monitor, so only when there isn’t an SPI transaction in progress can VSYS be read via the ADC.
