Just yesterday was looking at ESP32 custom board used to open/close gates which has super weak signal even when access point is only few meters apart... I found that there is empty place where external antenna connects - I think I can solder the connector and connect the antenna.
Is there any article out there that would help me do it? As I understand there needs to be some resistor that should be desoldered or existing link to on-board antenna cut.
