Unfortunately, I didn't read the wifi functions carefully.
esp32 is a memory and energy eater, currently unsuitable for "mobile" operation. BLE is unusable, unstable and unreliable.
I would choose a low-power, very reliable controller as an "official" device. For example the NRF52840 (I really like the Espruino MDBT42Q) with a Wifi (ESP) modul and with a mosfet "switch".

How is this related to esp32 and why it should be forgotten? From the basic info this can't do Wi-Fi, it can only passively scan (GPS and) Wi-Fi to determine location. And BTW they have wrong info about RAM, 52840 has only 256KB so maybe other info can be wrong too.
