Tkinter setup wizard for the V2X2MAP ITS-G5 Receiver bridge.
|

|
|
|
||
|
|
Steps:
|
||
|
|
1. Device — pick the serial port
|
||
|
|
2. Flash — write the bundled firmware
|
||
|
|
3. Done — the device derives its node-id from its own MAC automatically
|
||
|
|
|
||
|
|
Returns dict {port} to the caller.
