Fix print timeout for P15 single-byte success response#8
Merged
Conversation
The L11 protocol parseResponse() required data.length >= 2, silently discarding single-byte printer success confirmations (0xAA). The original Android app only requires length >= 1. This caused waitForPrintResult() to never resolve, leading to a 30s timeout. - Move success byte check before the length < 2 guard in parseResponse - Handle unexpected BLE disconnect as implicit print success - Add optional onDisconnect to BleConnection interface - Clean up dead ternary in buildPrintSequence
