How can I achieve wireless flash of an RPI Pico W board?
I need this because during testing of my device, I will need to tune it and flash the board frequently which will save time rather then connecting it to my PC all the time.

If you want to do this, you need to wireless flashing of an RPI Pico W board, you can utilize the Raspberry Pi Pico's built-in support for wireless programming through the UF2 (USB Flashing Format) bootloader. In order to do that:
Step 1: Prepare your RPI Pico W board: Make sure you have the necessary hardware components and connections in place for the initial setup. This includes power supply, USB cable, and any additional peripherals you might need.
Step 2: Update the UF2 bootloader: Ensure that your RPI Pico W board has the latest version of the UF2 bootloader installed. The UF2 bootloader is responsible for handling the wireless programming functionality.
Step 3: Connect to your PC: Connect your RPI Pico W board to your PC using a USB cable. This is required for the initial setup and subsequent wireless programming configuration.
Step 4: Put the board into wireless programming mode: Press and hold the BOOTSEL button (usually labeled "RUN" or "BOOTSEL") on the RPI Pico W board, then connect it to your PC using the USB cable. This will put the board into programming mode.
Step 5: Find the wireless programming drive: After connecting the board in programming mode, it should appear as a new drive on your computer. Open the drive to access its contents.
Step 6: Configure wireless programming: Locate the file named boot.py on the wireless programming drive and open it with a text editor. Modify the file to include your desired wireless programming settings. It might look for example like this:
import network
# Connect to your Wi-Fi network
wifi_ssid = "Your_Wi-Fi_SSID"
wifi_password = "Your_Wi-Fi_Password"
# Set up as an access point (optional)
ap_ssid = "Pico_Wireless_AP"
ap_password = "Pico_AP_Password"
def connect_to_wifi():
sta_if = network.WLAN(network.STA_IF)
sta_if.active(True)
if not sta_if.isconnected():
print('Connecting to WiFi...')
sta_if.connect(wifi_ssid, wifi_password)
while not sta_if.isconnected():
pass
print('Connected:', sta_if.ifconfig())
def create_access_point():
ap_if = network.WLAN(network.AP_IF)
ap_if.active(True)
ap_if.config(essid=ap_ssid, password=ap_password)
print('Access Point created:', ap_if.ifconfig())
# Connect to Wi-Fi network or create an access point
connect_to_wifi()
# create_access_point() # Uncomment if you want to set up an access point
Dont forget to modify the wifi_ssid and wifi_password variables with the credentials of your Wi-Fi network. Optionally, you can configure an access point by uncommenting the create_access_point() line and providing the desired ap_ssid and ap_password values.
Step 7: Save the boot.py file and eject the drive: Save the changes you made to the boot.py file and safely eject the wireless programming drive from your computer.
Step 8: Disconnect the RPI Pico W board from your PC: Once the drive is ejected, disconnect the board from your PC by removing the USB cable.
Step 9: Power the board using a suitable power source: Power up the RPI Pico W board using a power source such as a battery or power adapter, depending on your setup.
Step 10: Connect to the board wirelessly: Now that the wireless programming configuration is in place, you can connect to the RPI Pico W board wirelessly using the Wi-Fi network or access point settings you provided.
And lastly: Flash the board wirelessly: With the RPI Pico W board connected to your Wi-Fi networ.
Good luck to you :)
