[简体中文]

CapSule Sensor V3 uses WirelessBoot mode to download firmware, exchange information, and print logs through WiFi.

Enter downloading mode(WirelessBoot)

  1. Long press the indicator light of the device for 8 seconds until the Blue light of the device is always on.

Note

Some early devices may require a regular press of 16 seconds.

  1. Find “WirelessBoot_xxxx” on your PC and connect, the password is “heltec.org”.

  1. Enter 192.168.4.1 in your browser to navigate to the WirelessBoot configuration page.
