bool_t ble_att_opcode_is_client_to_server(enum ble_att_opcode_e opcode) [link]
This function is declared in ble/protocol/att.h source file, line 82.
this function retrieves whether ATT opcode is from client to server.
bool_t ble_att_opcode_is_response_expected(enum ble_att_opcode_e opcode) [link]
This function is declared in ble/protocol/att.h source file, line 91.
this function retrieves whether ATT opcode implies a response.
bool_t ble_att_opcode_is_signed(enum ble_att_opcode_e opcode) [link]
This function is declared in ble/protocol/att.h source file, line 100.
this function retrieves whether ATT opcode is signed.
uint8_t ble_att_opcode_operation(enum ble_att_opcode_e opcode) [link]
This function is declared in ble/protocol/att.h source file, line 73.
this function retrieves basic ATT opcode operation from opcode, ignoring if it is signed or unacknowledged.
