After the ESP32 board is initially flashed and has joined a LoRaWAN network, the firmware can update itself by OTA. This process is kicked off by sending a remote control command (see below) via LoRaWAN to the board. The board then tries to connect via WiFi to a cloud service (JFrog Bintray), checks for update, and if available downloads the binary and reboots with it. If something goes wrong during this process, the board reboots back to the current version. Prerequisites for OTA are: 1. You own a Bintray repository, 2. you pushed the update binary to the Bintray repository, 3. internet access via encrypted (WPA2) WiFi is present at the board's site, 4. WiFi credentials were set in ota.conf and initially flashed to the board. Step 2 runs automated, just enter the credentials in ota.conf and set `upload_protocol = custom` in platformio.ini. Then press build and lean back watching platformio doing build and upload.
- **over the air (OTA), upload via WiFi:**
If option *BOOTMENU* is defined in `paxcounter.conf`, the ESP32 board will try to connect to a known WiFi access point each time cold starting (after a power cycle or a reset), using the WiFi credentials given in `ota.conf`. Once connected to the WiFi it will fire up a simple webserver, providing a bootstrap menu waiting for a user interaction (pressing "START" button in menu). This process will be aborted by ESP32 hardware watchdog after *BOOTDELAY* seconds, ensuring booting the device to runmode. Once a user interaction in bootstrap menu was detected, the watchdog time will be extended to *BOOTTIMEOUT* seconds. During this time a firmware upload can be performed manually by user, e.g. using a smartphone in tethering mode providing the firmware upload file.
