First boot¶

After flash and RST, Meshtastic should start. The OLED should show UI (or a region-unset prompt).

Expect¶

• OLED activity on a board that had a working display before the flash.
• Serial boot lines such as SSD1306 found at address 0x3c.
• Status LED returns to a normal colour after RST (for example white).
• Bluetooth advertising for the mobile app (typical).

If the OLED worked before flashing and is black afterward, see Troubleshoot and reflash from Identify.

Power¶

On USB the board stays powered without pressing PWR. On battery, hold PWR until the board boots (check the silk on your kit).

Next: Configure.
