goTool

Host-side UART client for the Powerpod master ESP.

Full system documentation (roles, ESP-NOW, framing, protobuf): ../main/README.md.

Usage

cd goTool
go mod tidy
go run . -port /dev/ttyUSB0

Flag	Default	Description
`-port`	(required)	Serial port on master UART (GPIO2/3 adapter)
`-baud`	`921600`	Must match firmware `UART_BAUD_RATE`

Implements the VERSION command (MessageType = 3): sends framed 03, decodes protobuf UartMessage.version_response.
