The manufacturer data from a peripheral seems to be getting an extra byte... My peripheral is sending these bytes: 0x0c 0xff 0xe5 0x02 0x00 0x01 0x01 0x00 0x00 0x00 0x00 0x00 0x00 The 0c means there are 12 more bytes coming. The ff means it's a manufacturer message. The next 2 bytes are the manufacturer id. The next 9 bytes are the custom manufacturer data. Here's what I'm getting from CBCentralManager.didDiscoverPeripheral: advertisementData: { kCBAdvDataIsConnectable = 1; kCBAdvDataLocalName = "SQ-SPT-0021 432190009"; kCBAdvDataManufacturerData = {length = 12, bytes = 0xe50200000101000000000000}; kCBAdvDataRxPrimaryPHY = 0; kCBAdvDataRxSecondaryPHY = 0; kCBAdvDataServiceUUIDs = ( "00000100-34ED-12EF-63F4-317792041D17" ); kCBAdvDataTimestamp = "681852653.472335"; } ... here's what I would expect in the 'kCBAdvDataManufacturerData' vs. what I'm getting: 0x00 0x01 0x01 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01 0x01 0x00 0x00 0x00 0x00 0x00 0x00 I lined these up to hopefully show that there's an extra 0x00 byte at the beginning (this is clearer with more non-zero bytes, but I didn't want to make up data, and I don't have the old data available). Where is this extra byte coming from, and how can I get rid of it? Changing the peripheral data is a possibility here.
