Trying to power the board with a 9V battery through VIN. As the documentation says, it can take input voltage of 6-12 Volts, but when I connect the 9V battery, all it does is power the board on and nothing else happens.

Anyone know what I am doing wrong?

EDIT: I am stupid had the ground connected to the wrong pin thanks for the help everyone.

  • What kind of 9V battery? – Majenko Mar 12 at 12:22
  • Just a regular 9V E-Block Battery. – Amit Aalok Mar 13 at 0:41
  • Yes, but what chemistry? – Majenko Mar 13 at 0:42

Assuming you are using a 9V block battery: They don't deliver the current you need for the esp32 to run/create an access point/act as a client. What you can do is connect 6 AA batteries in a row (6*1.5V = 9V) and they will deliver a higher current than the 9V block.
