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.

The following commands were changed in the 0.6.7 release:

AT+BLEUARTTX

If the TX FIFO is full, the command will wait up to 200ms to see if the FIFO size decreases before exiting and

returning an ERROR response due to the FIFO being full.

AT+BLEURIBEACON

This command will go back to using the old (deprecated) UriBeacon UUID (0xFED8), and only the

AT+EDDYSTONEURL command will use the newer Eddystone UUID (0xFEAA).

AT+BLEKEYBOARD and AT+BLEUARTTX

These commands now accept '\?' as an escape code since 'AT+BLEKEYBOARD=?' has another meaning for the

AT parser. To send a single question mark the following command should be used: 'AT+BLEKEYBOARD=\?'

or 'AT+BLEUARTTX=\?'

AT+EDDYSTONEURL

This command now accepts an optional third parameter for RSSI at 0m value (default is -18dBm).

Running this command with no parameters ('AT+EDDYSTONEURL\r\n') will now return the current URL.

Key bug fixes in this release:

The FIFO handling for the Bluetooth UART Service was improved for speed and stability, and the TX and RF

FIFOs were increased to 1024 bytes each.

An issue where a timer overflow was causing factory resets every 4 hours or so has been resolved.

Fixed a problem with the GATT server where 'value_len' was being incorrectly parsed for integer values in

characteristics where 'max_len' >4

Version 0.6.6

The following AT commands were added in the 0.6.6 release:

AT+EDDYSTONEURL

Update the URL for the beacon and switch to beacon mode

AT+EDDYSTONEENABLE

Enable/disable beacon mode using the configured url

AT+EDDYSTONECONFIGEN

Enable advertising for the the Eddystone configuration service for the specified number of seconds

AT+HWMODELED

Allows the user to override the default MODE LED behaviour with one of the following options: DISABLE, MODE,

HWUART, BLEUART, SPI, MANUAL

AT+BLECONTROLKEY

Allows HID media control values to be sent to a bonded central device (volume, screen brightness, etc.)
