AT+CONNECTBOND

Scan for and initiates a connection with a selected bonded device. Works even if the peer bonded device is advertising with a Private Random Resolvable Address. Upon successfully connecting it will attempts to display the services of the peer device (if auto-discover services (ATDS) is on). The dongle must be in central or dual role.

Command	Syntax
AT+CONNECTBOND	AT+CONNECTBOND=*bonded address*

This command will do a scan for up to 12 seconds to see if the bonded address is advertising. It will also resolve any addresses it can with it's IRK (Identity Resolving Key) and check if any resolved address matches the bonded address. If it finds the bonded address, either advertising with a static address or Private Random Resolvable Address, it will stop the scan and connect to it.

The bonded address must be in the bonded list (AT+GETBOND).

Example:

Default Mode

Verbose Mode

AT+CONNECTBOND=40:48:FD:EA:E8:38
Trying to connect...

Identity Address: 40:48:FD:EA:E8:38

AT+CONNPARAM

Sets or displays preferred connection parameters. When run while connected will update connection parameters on the current target connection.

Command	Syntax
AT+CONNPARAM	AT+CONNPARAM
	or
	AT+CONNPARAM=intv_min=intv_max=slave_latency=supervision_timeout

Setting connection parameters when not connected will result in using set connection parameters as the default when using the AT+GAPCONNECT command without arguments.

Querying connection parameters using the command without parameters will display the current set preferred connection parameters. When used while connected will instead show current active connection parameters.

Connection Parameter	Range
intv_min (Connection Interval Min)	7.5ms-4000ms
intv_max (Connection Interval Max)	7.5ms-4000ms
slave_latency (Slave Latency)	0-499*
supervision_timeout (Supervision Time-out)	100ms-32000ms

(*) The slave latency can also not exceed (( supervision_timeout / (intv_max * 2)) -1).

The CI min and CI max as shown upon connection event are calculated as such: (interval in ms) * 100 / 125. So if you for example set the intv_min to 30 it will show as CI min of 24.

Example:

Default Mode

Verbose Mode

AT+CONNPARAM
Connection Interval min = 24
Connection Interval max = 24
Slave Latency = 1
Supervision Timeout = 1000ms.

AT+CONNSCANPARAM

Set or queries the connection scan window and interval used.

Command	Syntax
AT+CONNSCANPARAM	AT+CONNSCANPARAM=*scan intv ms=scan win ms*
	AT+CONNSCANPARAM

Scan Interval is the duration of time between scans.
Scan Window determines how long to scan for at each interval.
The Scan Window parameter must be equal or smaller than the Scan Interval.

The scan interval and window can be set in steps of 0.625ms. Allowed values for interval span in the range of 2.5ms to 10240ms. This command set the scan parameters used for initiated connections.

Return scan window and scan interval values are in units of 0.625ms and can be converted to ms like this:
return value * 0.625
So for example 160 * 0.625 = 100ms
and 320 * 0.625 = 200ms

Example:

Default Mode

AT+GAPADDRTYPE

Sets or queries what address type the dongle will use. Changing address type cannot be done while advertising or while connected to other devices.

Command	Syntax
AT+GAPADDRTYPE	AT+GAPADDRTYPE=address_type_code
	or
	AT+GAPADDRTYPE

Table of supported address types:

Address Type	Description	Code
PUBLIC_STATIC_ADDRESS	Public Static Address	1
PRIVATE_STATIC_ADDRESS	Private Static Address	2
PRIVATE_RANDOM_RESOLVABLE_ADDRESS	Private Random Resolvable Address	3
PRIVATE_RANDOM_NONRESOLVABLE_ADDRESS	Private Random Non-resolvable Address	4
PRIVATE_CNTL	Private Random Resolvable address using Bluetooth LE Privacy v1.2	5

Non-static addresses will renew themselves every 150 seconds.
When 'Private Non-resolvable Address' is set BleuIO will not be able to connect to other devices or advertise in any other mode than in Non-connectable mode: GAP_CONN_MODE_NON_CONN. This will be chosen by default if starting advertising with the AT+ADVSTART command (without parameters) if Private Random Non-resolvable Address is set.

About Bluetooth LE Privacy:

"When Bluetooth LE Privacy is in use and advertising packets contain randomly generated MAC addresses disguising your device’s identity, the real MAC address remains hidden away. But what use is this if the outside world sees your device as having a different address?

The answer lies in the Bluetooth pairing process—Bluetooth® users are familiar with this process. Pairing indicates you trust the other device and want to interact with it. For example, if you pair your activity tracker with your phone, from that point on, the phone will have a special, trusted relationship with the tracker. What happens is much more involved but after pairing, the two devices will possess various encryption keys, one of which is concerned with privacy. This key is called the Identity Resolution Key (IRK). IRK allows the first device to translate those special, random MAC addresses which appear in the advertising packets from the second device, to the real MAC address in the second device. This capability is only in devices you have explicitly trusted."
- From "Bluetooth Technology Protecting Your Privacy"

AT+GAPCONNECT

Initiates a connection with a specific slave device. Upon successfully connecting it will attempts to display the services of the peer device (if auto-discover services (ATDS) is on). The dongle must be in central or dual role.

Command	Syntax
AT+GAPCONNECT	AT+GAPCONNECT=*[addr_type]slave address*
	AT+GAPCONNECT=*[addr_type]slave_address=intv min:intv max:slave latency:supervision timeout:*
	AT+GAPCONNECT=deviceIndex!
	AT+GAPCONNECT=deviceIndex!=intv min:intv max:slave latency:supervision timeout:

Address Type
[0]	PUBLIC_ADDRESS
[1]	PRIVATE_ADDRESS

If no connection parameters are entered then the parameters set with the AT+CONNPARAM command will be used, otherwise the default values will be used.
Default values:
intv min=30
intv max=30
slave latency=0
supervision timeout=1000

Connection Parameter	Range
intv min (Connection Interval Min)	7.5ms-4000ms
intv max (Connection Interval Max)	7.5ms-4000ms
slave latency (Slave Latency)	0-499*
supervision timeout (Supervision Time-out)	100ms-32000ms

(*) The slave latency can also not exceed ((supervision timeout / (intv max * 2)) -1).

The CI min and CI max as shown upon connection event are calculated as such: (interval in ms) * 100 / 125. So if you for example set the intv_min to 30 it will result in a CI min of 24.

If a connection fails to be established and causes a disconnection event right after a connection event, the dongle will now automatically try to reconnect instead of showing the disconnecting event. The response shown will be: "Connection failed to be established. Reconnecting..." It will try up to 6 times. If it fails after that this response will be shown: "DISCONNECTED. FAILED TO ESTABLISH CONNECTION!" along with a disconnection event.

This command has a two-part response.
First the "Trying to connect..." response is the acknowledgement that the command has been accepted and will follow immediately after the command has been run.

The "handle_evt_gap_connected:..." response will trigger afterwards when the operation is completed. If auto-discover services (ATDS) is not turned off then all services will be discovered as well and the event "handle_evt_gattc_browse_completed:..." will trigger when it's done.

Be aware that between the first and second response other events can trigger, for example, notifications or write operations.

Instead of using MAC Address (type and address) as a parameter it is possible to use the index shown in the scan results after running AT+GAPSCAN. (For verbose mode use the command ATSIV to show index in the scan result). The indexes will reset when doing a new scan.

AT+GAPPAIR

Starts a pairing (AT+GAPPAIR) or bonding procedure (AT+GAPPAIR=BOND). Depending on whether the device is master or slave on the connection, it will send a pairing or a security request respectively.
Only usable when connected to a device.

Command	Syntax
AT+GAPPAIR
	AT+GAPPAIR=BOND
	or
	AT+GAPPAIR

Important!
Firmware Ver <= 2.7.4:
BleuIO can save the bonding information of up to 8 devices. When 8 devices had been stored no new bonding can be done until the user manually removed one or all bonding information using the AT+GAPUNPAIR command.
> Firmware Ver >= 2.7.5:
BleuIO can save the bonding information of up to 16 devices. When 16 devices had been stored the user can still bond. The BleuIO will remove the bonding information of the first bonded device that was added to the list that isn't currently connected.
Since BleuIO support up to 8 connections at the time there will always be at least 8 bonded devices that isn't currently connected. The first device that was bonded will be removed to make room for the new bonded device information.

AT+SCANPARAM

Set or queries the scan parameters used.

Command	Syntax
AT+SCANPARAM	AT+SCANPARAM=*scan mode=scan type=scan intv ms=scan win ms=filt dupl*
	AT+SCANPARAM

Scan Mode

Acceptable Value	Meaning
0	General-Discoverable mode
2	Observer mode (default)

In General-discoverable mode the scan will stop after 10 seconds while in Observer mode it continues until stopped.

Scan Type

Acceptable Value	Meaning
0	Active Scan type (default)
1	Passive Scan type

Passive scan only scans Advertising Data.
Active scans Advertising Data and requests Scan Response Data.

Scan interval and window

Scan Interval is the duration of time between scans.
Scan Window determines how long to scan for at each interval.
The Scan Window parameter must be equal or smaller than the Scan Interval.

The scan interval and window can be set in steps of 0.625ms. Allowed values for interval span in the range of 2.5ms to 10240ms. This command set the scan parameters used for scans used by the commands AT+GAPSCAN, AT+FINDSCANDATA and AT+SCANTARGET.

Return scan window and scan interval values are in units of 0.625ms and can be converted to ms like this:
return value * 0.625
So for example 160 * 0.625 = 100ms
and 320 * 0.625 = 200ms

Filter Duplicate

AT+SECLVL

Sets or queries what minimum security level will be used when connected to other devices.
When used while connected will trigger a pairing request. When used while not connected, sets what minimum security level the dongle will demand when connecting to another device. If the other device does not meet the security requirement, the dongle will disconnect.
Querying security level, while connected, will show actual security level. While not connected, querying will show what minimum security level has been set that the dongle will require when connecting to another device. Note that what security level is supported is dependent on what Input/Output capability is set. See the table for more information.
