picowota, kinda sounds like you're speaking Belter
This project implements a bootloader for the Raspberry Pi Pico W for the OpenTrickler Project

Once you've got the picowota bootloader installed on your Pico, you can use
the https://github.com/usedbytes/serial-flash tool to upload code to it.
As long as the Pico is "in" the picowota bootloader (i.e. because there's no
valid app code uploaded yet, or your app called picowota_reboot(true);), you
can upload an app .elf file which was built by picowota_build_standalone():
If using the AP mode, the Pico's IP address will be (at the time of writing) 192.168.4.1/24, and the connected device's something in the same subnet. Otherwise it depends on your network settings.
(Assuming your Pico's IP address is 192.168.1.123):
serial-flash tcp:192.168.1.123:4242 my_executable_name.elf
After uploading the code, if successful, the Pico will jump to the newly uploaded app.
