Command Disallowed 0x0C The Controller can't carry out the command in its current state. 2.12
Rejected due to Limited Resources 0x0D A connection or other request was turned down because resources are limited. 2.13
Rejected Due To Security Reasons 0x0E A connection or other request was turned down because security requirements, such as pairing, weren't met. 2.14

Remote User Terminated Connection 0x13 The user on the remote device ended the connection or stopped broadcasting. 2.19
Remote Device Terminated Connection due to Low Resources 0x14 The remote device ended the connection because it was low on resources. 2.20
Remote Device Terminated Connection due to Power Off 0x15 The remote device ended the connection because it is about to power off. 2.21
Connection Terminated By Local Host 0x16 The local device ended the connection, stopped synchronizing to a broadcaster or stopped broadcasting. 2.22
Repeated Attempts 0x17 Authentication or pairing is refused because the last failed attempt was too recent. 2.23
Pairing Not Allowed 0x18 The device doesn't allow pairing, for example outside a window the user opened for it. 2.24
Unknown LMP PDU 0x19 The Controller received an LMP PDU with an opcode it doesn't know. 2.25

Instant Passed 0x28 An LMP or LL PDU with an instant arrived too late: the instant has already passed. 2.40

Parameter Out Of Mandatory Range 0x30 A parameter value is outside the mandatory range, and the recipient doesn't accept it. 2.47

Role Switch Failed 0x35 A role switch failed and the original piconet structure was restored. 2.50
Extended Inquiry Response Too Large 0x36 The extended inquiry response, with the requested FEC, doesn't fit any packet type the Controller supports. 2.51
Secure Simple Pairing Not Supported By Host 0x37 The IO capability exchange was rejected because the sending Host doesn't support Secure Simple Pairing. 2.52
Host Busy - Pairing 0x38 The Host is busy with another pairing and can't take on this one; try again later. 2.53
Rejected due to No Suitable Channel Found 0x39 The Controller couldn't work out a suitable value for channel selection. 2.54
Controller Busy 0x3A The Controller was too busy to process the request. 2.55

Advertising Timeout formerly Directed Advertising Timeout 0x3C Advertising for a fixed duration ended, or directed advertising ended without a connection. 2.57
Connection Terminated due to MIC Failure 0x3D A connection or synchronization ended because a received packet failed its message integrity check. 2.58

Coarse Clock Adjustment Rejected but Will Try to Adjust Using Clock Dragging 0x40 The Central can't make a coarse piconet clock adjustment now and will use clock dragging instead. 2.61
Type0 Submap Not Defined 0x41 The LMP PDU was rejected because no Type 0 submap is defined. 2.62
Unknown Advertising Identifier 0x42 The command names an advertising or sync handle that doesn't exist. 2.63
