Hi,
I am an embedded software engineer with more than 6 years of experience in Raspberry Pi based programming.
I have worked on Raspberry Pi-based projects many times, including Pi zero w.
I can easily make this a background process after reviewing the code for optimization. So once this is done, it can be run at the boot, without any manual intervention. I have done lot of similar work before.
I also have a raspberry Pi with me for test this setup.
Looking forward to hearing back from you.
Thank you
Anusha
