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

Fixed systick to ms calculation

Fixed all tests with google eddystone validator except for writing tx_power = 1 dB (not

valid on nrf51)

Fixed a bug where writing from the central does not update the value on the

characteristic correctly

Fixed an issue with HID examples, where when paired with Central, a disconnect then

reconnect could not send HID reports anymore

Version 0.6.7

The following AT commands were added in the 0.6.7 release:

AT+BLEUARTFIFO

Returns the number of free bytes available in the TX and RX FIFOs for the Bluetooth

UART Service.
