Revision History

Rev #

Date

Description

5.0.6.0

11/27/2018

New Features:

▪BT5.0 support 2Mbps and Long Range PHY support, extended advertising

packets, LE Secure Connections pairing.

▪Up to 8dBm output power now supported.

▪BRSP throughput up to 50kBps.

▪Single mode modules can now be connected to 5 devices simultaneously (1

as a peripheral and 4 as a central).

▪Configurable MTU up to 247 bytes.

▪USB and NFC support.

▪Dedicated Over the Air Firmware Update (DFU) service. Firmware updates

no longer done through BRSP service.

New Commands:

▪AT? Used to display a list of all available commands.

▪ATSCFG Allows reading/writing the entire config in only a few commands.

▪ATSDPL Replaces ATSPL to set default output power level. TX_Power is

set separately for Advertising and Scanning, RX_Sensitivity is fixed so that

parameter has been removed.

▪ATSCPL Sets the current power level for an active connection.

▪ATSUSB Allows USB serial ports to be enabled/disabled.

▪ATSNFC Allows NFC pairing to be enabled/disabled.

▪ATSPIOL Allows temporary changing of PIO output level.

▪ATSDMLE Allows Channel_Map to be set for ATDMLE and default BRSP

mode to be set.

▪ATSDMTU Allows the default MTU (Maximum Transmission Unit) to be set.

▪ATSSPHY Sets the PHYs the module will accept if a connection PHY

update is requested by another device.

▪ATSCPHY Requests to change the current PHY for a connection.

▪ATCRSSI Allows the RSSI to be continuously sampled when in a

connection.

▪ATPKC Allows module to respond to a PK_REQ event that requires

confirmation to complete a numeric comparison as part of LESC pairing.

▪ATGRM - GATT Read Multiple. Allows multiple characteristics to be read at a

time. This feature is only supported in the client role, so it is not possible to

use ATGRM to another BR-LE5.0-S1 or PAN1780-AT module.

▪ATSBASL Used to set the BAS battery level when in manual mode.

▪ATBRSPW Allows BRSP data to be sent via commands instead of a

stream.

▪ATDTM Allows device to enter Direct Test Mode for RF testing.

▪ATTEST Puts the device into an AT command test mode where ATTXT and

ATRXT can be used.

▪ATBOOT Used to run the bootloader.

▪ATSBOOT Used to configure the bootloader.

▪ATSDFU Used to enable/disable the Over the Air Firmware Update service.

New Events:

▪EXT_DISCOVERY Added to support BT5.0 extended advertising.

▪MTU Added to support changing the connection MTU (maximum

transmission unit). By default, this will now print after a CONNECT event

once the MTU has been negotiated. Can be disabled using the ATSRM

command.

▪PHYU Added to support the different BT5.0 PHYs and being able to change

the current PHY during a connection.

▪BRSPD A new BRSP data event that can be enabled in ATSBRSP to have

brsp data be delivered in events instead of a raw stream of data.

▪RSSI Similar behavior as before, but now considered an event.

Document Format Changes:

▪All dual mode commands have been removed to simplify the document.

▪The location of some of the events/commands in the document has changed

to better group related events/commands together.

Response Format Changes:

▪Leading zeroes have been removed from response values.

Optional Parameters:

▪All optional parameters will use the default value if not specified. In version

3.5 a change was made so that for commands that store in flash with optional

parameters, if an optional parameter was not specified then the current value

was used. This has not been implemented in this version.

Address Format Changes:

▪The BT5.0 Address and address type have now been combined into a single

parameter for all commands/events using an address. See BT5.0 Address

Format for more details.

PIO Functionality Changes:

▪Pulsing PIO_14 can be used to start/stop advertising.

▪PIO_7 is now an LED output that can be configured to blink at a desired rate

or to show sleep status using ATSZ.

▪PIO_8 is now an LED output that by default will flash once when a command

is received and can also be configured to blink at a desired rate.

▪ATRFO used to enable RF RX/TX debugging on PIO 8/9 and now defaults to

19/20. The PIOs can also be specified through the command now.

▪Unused PIOs will now default to a disconnected state instead of a pulled

down input state.

Event Format Changes:

▪RESET - Reset reason added. FACTORY_RESET will no longer be printed

on a factory reset. Factory_Reset is now a value in the RESET event.

▪DISCOVERY - COD/Addr_Type value removed.

▪CONNECT Conn_Type replaced with Conn_Role value. Pair_Status

changed to Paired.

▪PAIR_REQ Added Conn_Handle value and removed Pairing_Type value.

▪PAIRED Added Conn_Handle, Bonded and Security_Level values, removed

Pairing_Status value.

▪PAIR_FAIL Added Conn_Handle value.

▪PK_REQ Added Conn_Handle value.

▪PK_DIS Added Conn_Handle and Confirmation_Required values.

▪GATT_VAL Added Value_Format value.

▪BRSP event now reports TX_Mode and RX_Mode.

Command Changes:

▪ATSRM - Individual events can now be disabled using the

Response_Event_Flags parameter.

▪ATCFG? The order of the response for the command has been changed to

match the order of the commands in the document.

▪ATSFC - Storing of last connected address can now be disabled to prevent

writing to flash after every connection to a different device. If automatically

storing to flash has been disabled through ATSFC, an individual command

character to the end of the command string, for example

ATSN#,NewModuleName<cr>.

▪ATZ - Module can now be put into a shutdown state using new Shutdown

parameter.

▪ATSZ - Added Shutdown_PIO_State parameter to set the state of the IO in

shutdown mode.

▪ATSAT Added Privacy_Type and Private_Addr_Cycle_Time parameters.

Resolvable private random address no longer considered an address type but

can be enabled through the Privacy_Type parameter.

▪ATSDBLE Removed the Bridge parameter as this is not supported (was

only supported on the dual mode module previously).

▪ATSPL Replaced by ATSDPL and now TX_Power is set separately for

Advertising and Scanning, RX_Sensitivity is fixed so that parameter has been

removed.

▪ATSPIO Added Pull_Drive_Strength parameter to allow pull ups/downs for

inputs and drive strength for outputs.

▪ATSLED 2 more LEDs can now be configured: PIO_7, PIO_8.

▪ATADC? Added support for changing Resolution, Gain and Acquisition

Time.

▪ATDSLE/ATDSDLE ATDSDLE removed, direct advertising can now be

done using ATDSLE with new Direct_Addr and Direct_Duty_Cycle

parameters.

▪ATSDSLE Added new Ad_Types and new params to support extended

advertising.

▪ATSDSTLE Connected_Ad_Interval can now be set as low as 20ms.

▪ATSDSDLE Can now set data for Extended Advertising Data.

▪ATDILE Added Extended_Primary_Phys parameter to allow scanning for

extended advertising packets. By default, if not specified the module will

discover both non-extended and extended ad packets on the 1Mbps PHY.

▪ATSDILE Max_Devices can now be set up to 50, Channel_Map parameter

added.

▪ATSDITLE Timeout now specified in seconds.

▪ATSDIF Added Discovery_Type_Format to allow Discovery_Type to be

formatted in the standard format, as a bitfield, or as a string. Also added

Global_Format parameter to allow DISCOVERY and EXT_DISCOVERY

events to be formatted the same instead of as 2 separate events.

▪ATDMLE Added Extended_Primary_Phys parameter to allow connecting to

a device that is advertising using extended ad packets.

▪ATSDMTLE Timeout now specified in seconds.

▪ATCS? Response changed: Replaced Conn_Type with Conn_Role,

Pairing_Status with Security_Level. Added Conn_Interval, Slave_Latency,

Supervision_Timeout, MTU, RX_PHY, TX_PHY, and TX_Power.

▪ATSPLE Added LESC parameter to enable/disable LE Secure Connections.

Sync_White_List now enabled by default.

▪ATPKR Address can no longer be specified, only Conn_Handle.
