android - AltBeacon setBeaconLayout()

Question

我想知道信标代码代表什么。我的意思是，据我所知，它应该识别信标布局。这是否意味着我可以自定义任何类型的布局并为其分配任何类型的信标代码？我的意思是，我可以写这样的东西吗:

setBeaconLayout("m:2-3=abcd,i:4-13,i:14-23,p:24-24,d:25-25")?

谢谢你的帮助

Answer 1

根据 AltBeacon docs :

m - matching byte sequence for this beacon type to parse (exactly onerequired)

s - ServiceUuid for this beacon type to parse (optional, only forGatt-based beacons)

i - identifier (at least one required, multiple allowed)

p - power calibration field (exactly one required)

d - data field (optional, multiple allowed)

x - extra layout. Signifies that the layout is secondary to a primarylayout with the same matching byte sequence (or ServiceUuid). Extralayouts do not require power or identifier fields and create Beaconobjects without identifiers.

Example of a parser string for AltBeacon:

"m:2-3=beac,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"

This signifies that the beacon type will be decoded when anadvertisement is found with 0xbeac in bytes 2-3, and a three-partidentifier will be pulled out of bytes 4-19, bytes 20-21 and bytes22-23, respectively. A signed power calibration value will be pulledout of byte 24, and a data field will be pulled out of byte 25.

这是一个list一些信标布局
