ESP32: Migrate to Arduino 3.x (pioarduino) (#9122)

* Migrate esp32 families to pioarduino platform * ESP32c6 align text.handler_execute same as C3 * Use pioarduino `develop` The latest fixes and the latest bugs! * preliminary esp32p4.ini * pioarduino: Update LovyanGFX Includes Manuel's recent commit * pioarduino 3.3.6 * pioarduino 3.3.6 *release* chasing the release * pioarduino: Fix OG ESP32 duplicate libs * pioarduino: T-Beam 1W CDC mode * pioarduino: disable network provisioning (wifiprov) * pioarduino: use legacy esptoolpy naming (forward-compatible) * Update lovyangfx from `develop` commit to 1.2.19 * fix esp32p4.ini * check for esp32 w/ wifi * esp32-p4 specific adaptations * Switch to meshtastic/esp32_https_server fork (idf5 branch) * don't ignore esp_lcd * config for MUI * fix/workaround SDMMC * revert a6f6175, update to 3.3.8 * enable esp_hosted for esp32-p4 (experimental) * Pioarduino 55.03.38-1 * NimBLE-Arduino -> Arduino "BLE" (3.3.x) migration (#10164) * NimBLE-Arduino -> Arduino "BLE" (3.3.x) migration * More NimBLE * Fix Device Name in ATT Read Request (0x2A00). Device Name is exposed in two places: - Advertisement data: this is set properly in startAdvertising. - GATT attribute Device Name (0x2A00). This one is handled internally in NimBLE and comes from ble_svc_gap_device_name_set. This is set initially, but then BLEDevice::createServer calls ble_svc_gap_init which resets the device name. This causes the device to apparently "change name after pairing": < ACL Data TX:... flags 0x00 dlen 7 #113 [hci0] 14.241149 ATT: Read Request (0x0a) len 2 Handle: 0x0003 Type: Device Name (0x2a00) > ACL Data RX: Handle 2048 flags 0x02 dlen 11 #115 [hci0] 14.269050 ATT: Read Response (0x0b) len 6 Value[6]: 6e696d626c65 # "nimble" Workaround this by setting the device name once again after BLEDevice::createServer. * Temporarily lower CORE_DEBUG_LEVEL to INFO to avoid triggering an apparent ESP-IDF Bluetooth bug when re-connecting to Pixel 8 Android devices. Initial pairing works, but after ESP32 is rebooted, phone fails to reconnect. Meshtastic app shows it as disconnecting immediately. LightBlue shows a more detailed error "Peripheral Connection - Warning: onConnectionStatusChange: status 61" (0x3D - MIC Failure). Bug report to Espresssif: https://github.com/espressif/esp-idf/issues/18126#issuecomment-4286197744 * Temporarily disable ble_gap_set_data_len, causes crash with Pixel 8 Android reconnect. Crash looks like this: [ 11966][E][BLEAdvertising.cpp:341] setScanResponseData(): ble_gap_adv_rsp_set_data: 22 [ 11975][E][BLEAdvertising.cpp:1554] start(): Host reset, wait for sync.

(#10235) * Re-enable littlefs json manifest This works locally again :) Not sure what changed * Re-add tool-mklittlefs * sensecap indicator fixes after upgrade arduino-esp & lovyanGFX libs * hackaday fix * robot tbeam cache error fix Co-authored-by: Copilot <copilot@github.com> * trunk fmt * ignore trunk * BLEDevice::deinit() added Co-authored-by: Copilot <copilot@github.com> * platformio-custom: Modify mtjson target dependency to prevent fake-success.

Align .text.handler_execute section to 4 bytes and update watchdog timer core mask configuration Co-authored-by: Copilot <copilot@github.com> * tlora-c6: Disable Screen MESHTASTIC_EXCLUDE_SCREEN=1 on tlora-c6. It doesn't have a screen, and this gets it compiling again (saving flash). * Use mverch's iram_memset hack for all OG-ESP32 * Refactor watchdog timer initialization and handling * use adc_channel_t in variant.h * Fix variant headers * More idiomatic default ethernet that doesn't break the build * Elecrows: Delete problematic variant.cpp Not needed after USE_ETHERNET_DEFAULT --------- Co-authored-by: mverch67 <manuel.verch@gmx.de> Co-authored-by: Manuel <71137295+mverch67@users.noreply.github.com> Co-authored-by: Catalin Patulea <cronos586@gmail.com> Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: vidplace7 <1779290+vidplace7@users.noreply.github.com> Co-authored-by: Copilot <copilot@github.com> Co-authored-by: thebentern <9000580+thebentern@users.noreply.github.com> Co-authored-by: Ben Meadors <benmmeadors@gmail.com>
