ATT, attribute Protocol, protocol for discovering, reading, and writing to-end devices (for BLE devices) 1 Introduction
ATT allows a device to provide a set of attributes with associated values as a serverLet the device as a client to discover, read, write these attributes, and the server can actively notify the client

[Att $ = val]. If the end character of the attribute value represented by att is the character specified by val, this style is used for this element.
Assembly languages depend on the architecture. In Linux, the compiled assembly by GCC is an ATT syntax assembly by default. This article mainly introduces ATT Assembly: operand length, immediate number representation method, register reference, operand sequence, symbol constant, memory Reference.
1. The length of the operand
The length of the operand is expressed by the symbol after the instruction in B
immediate suffix are labeled "H" and "B" respectively, while at/T, hexadecimal immediately preceded by "0x", table 2.2 gives several corresponding examples.Table 2.2 The difference between Intel and the-t prefix

2. Direction of the operandIntel is in the opposite direction of the/t operand. In Intel syntax, t
