AT+NVMREADRAW=offset,size binary data

Binary data (instead of ASCII) is returned, ending with "OK\r\n". It is non-printable but less overhead and easier to

use in some situations.

AT+BLEHIDGAMEPAD=x,y,buttons

X is LEFT, RIGHT: X=-1 LEFT is pressed, X=1 RIGHT is pressed, X=0 no pressed

Y is UP, DOWN: Y=-1 i UP, Y=1 is DOWN, Y=0 no pressed

Button [0x00-0xFF] is a bit mask for 8 button 0-7

AT+GAPCONNECTABLE=on/off/1/0

Allow/disallow connection to the device

AT+EDDYSTONESERVICEEN

Add/remove EddyStone service to GATT table (requires reset)

AT+EDDYSTONEBROADCAST=on/off/0/1

Start/stop broadcasting url using settings from NVM

AT+BLEBATTEN=on/off/1/0

Enable battery service. Reset required due to the service change.

AT+BLEBATTVAL=percent

Updates the Battery level, percent is 0 to 100

The following commands were changed in the 0.7.0 release:

AT+GATTADDCHAR

Added a DATATYPE option to indicate the data type for the GATT characteristic's payload. Valid option are:

AUTO (0, default), STRING (1), BYTEARRAY (2), INTEGER (3)

Added characteristic user description option via the DESCRIPTION flag

Added characteristic presentation format support via the PRESENTATION flag

AT+GAPINTERVALS

Added a new 'adv_lowpower_interval' parameter, default value is 417.5 ms. Current arguments are

now: min_conn, max_conn, adv_interval, adv_timeout, adv_lowpower_interval

Key bug fixes and changes in this release:

Significant BTLE UART speed and reliability improvements

Added callback support (work in progress) for:

BLE UART RX

GATT Characteristic(s) RX

MIDI RX

Connect/Disconnect

Increased MAX_LEN for each characteristic from 20 to 32 bytes

Changed the default GAP parameters:

Advertising interval = 20ms

Min connection interval = 20 ms

Max connection interval = 40 ms

Increased the maximum number of CCCDs saved to flash from 8 to 16

Eddystone config service disabled by default

Removed AT+EDDYSTONEENABLE to avoid confusion

Changed advertising timeout for Eddystone to 'unlimited'

Fixed Write-No-Response characteristic property, which wasn't being handled properly

Fixed timing constraints to meet Apple design guidelines
