I have an ESP-32 Dev board setup in Access Point mode to control two door openers on an older shed on my farm.   I have another ESP-32 Dev board setup as BLE to control a door opener and lights in my farm shop.  I used Remote XY to create the custom apps for my iPhone, iPad and Android tablet.  These work fine but the range is limited.  I have also purchased an ESP-32 Cam board which has the provision for an external antenna but haven't worked with it yet.  An external antenna should improve my range in Access Point mode.  Will it help the range in BLE mode?  Are there ESP-32 Dev boards that have the external antenna option without the camera?  The ESP-32 was cheap enough that I don't need the camera but I do need at least 6 GPIOs for the old shed situation.

As far as the esp32 wroom, it is a DevKit. Just type in DOIT and use that, or via the Tools menu goto  Board etc and the top 4 are all generic esp32, one for each model and your model is the lowest on the list.

To 'wipe' the board, create an empty sketch and upload it.

Can't answer the rest of your questions.

@videogame95 Why did you jump on someone else Topic? Your topic is new, read the help (over to the right) and in the future post accordingly.

I got a message that a new reply was posted to my original post from 2021.  I have since found a Dev board that contains an ESP 32 and four relays.  The board has an external antenna and can be powered by 12VDC. The board handles the various voltage levels and opto-isolators to the relays. This fit my situation nicely since I needed four relays, an external antenna for range and could use a 110VAC to 12VDC adapter.  I have the ESP setup in Access Point mode since I do not have internet availability around my sheds.  I used the RemoteXY website to create the screen layout.

The ESP32 board is housed in a plastic electrical box outside the shed.  The antenna runs out the bottom of the enclosure.  A piece of PVC pipe goes through the shed wall.  This pipe carries the power and ground in to the ESP32 board and the outputs from the relays into the shed where they attach to the original 3 button switch and latching light relay. This means I can control the door and lights from the phone or from actual switches inside the building.  As I approach the building, I need to check my settings to determine if my phone has "latched" on to the proper WiFi network.  If not I manually change it and then go to the RemoteXY App on my phone. Once I choose the proper item, communication is established and the screen layout is transferred to the phone so that I can use it.

This works very well.
