# OTA
|
|
## Protocol:
|
|
READERID is 5 Digits
|
|
1. Hello: Topic="fabreader", Payload="READERID"
|
|
1. Start: Topic="fabreader/READERID/startOTA", Payload=UID of Card
|
|
1. Request: Topic="fabreader/READERID/requestOTA", Payload=256 Bytes APDU Command
|
|
1. Response: Topic="fabreader/READERID/responseOTA", Payload=256 Bytes APDU Response
|
|
1. Stop: Topic="fabreader/READERID/stopOTA", Payload=NULL
|
|
1. Cancel: Topic="fabreader/READERID/cancelOTA", Payload=UID of Card
|
|
1. Restart: Topic="fabreader/READERID/restartOTA", Payload=NULL
|
|
|
|
## Procedure:
|
|
After Start Reader sends "Hello".
|
|
|
|
After new Card is on Reader:
|
|
"Start" -> to Server
|
|
"Request" <- from Server
|
|
"Response" -> to Server
|
|
|
|
Repeat Request and Response until:
|
|
"Stop" <- from Server
|
|
"Cancel" -> to Server
|
|
|
|
If FabReader works as deadmen switch the OTA connection is not stopped and the next check can be started with restartOTA.
|
|
If DESFire Card uses Random UID the UID changes every new connection, so the connections stays active until the server restartsOTA and performs new OTA.
