Wifi/Bluetooth Research: Wifi/Bluetooth: Research & Suggested Parts

Investigate viability of backpack:

  • Is it needed to have both ESP-01F (backpack) and ESP32-Pico (main MCU)

    • Ask in discord ELRS and watch videos (research)

  • Figure what communication looks like between ESP32-Pico and TX16 (4 pin connector, likely UART)

  • Figure out firmware update over UART for ESP-32 (only if we need the ESP-01F)

  • Figure out antenna for ESP ICs, (PCB antenna modules? custom designed? coax to an external antenna?)

    • ESP32-PICO (SOIC chip, need to make own PCB antenna & USB-UART bridge)

    • ESP32-WROVER (module, has its own PCB antenna, still need USB-UART bridge)

    • ESP32 Dev board (may or may not have antenna, has USB-UART bridge)

    • Best to avoid COAX to an external antenna, only need short range for WiFi OTA updates

Next steps:

  • Investigate how firmware is mapped to the ESP, how is it configured/flashed

TX Chip: https://semtech.my.salesforce.com/sfc/p/#E0000000JelG/a/2R000000HoCW/8EVYKPLcthcKCB_cKzApAc6Xf6tAHtn9.UKcOh7SNmg

Next steps:

  • Figure if shielding is necessary

  • Ties in to code, figure out firmware

  • No labels
