Codebase Revision: 0.3.0

Parameters: If updating the GAP intervals, the following comma-separated values can be

entered:

Minimum connection interval (in milliseconds)

Maximum connection interval (in milliseconds)

Fast Advertising interval (in milliseconds)

Fast Advertising timeout (in seconds)

>= 0.7.0: Low power advertising interval (in milliseconds), default = 417.5 ms

Please note the following min and max limitations for the GAP parameters:

Absolute minimum connection interval: 10ms

Absolute maximum connection interval: 4000ms

Absolute minimum fast advertising interval: 20ms

Absolute maximum fast advertisting interval: 10240ms

Absolute minimum low power advertising interval: 20ms

Absolute maximum low power advertising interval: 10240ms

Output: If reading the current GAP interval settings, the following comma-separated

information will be displayed:

Minimum connection interval (in milliseconds)

Maximum connection interval (in milliseconds)

Advertising interval (in milliseconds)

Advertising timeout (in milliseconds)

To save power, the Bluefruit modules automatically drop to a lower advertising rate

after 'fast advertising timeout' seconds. The default value is 30 seconds ('Fast

Advertising Timeout'). The low power advertising interval is hard-coded to

approximately 0.6s in firmware < 0.7.0. Support to control the low power interval

was added in the 0.7.0 firmware release via an optional fifth parameter.

If you only wish to update one interval value, leave the other comma-separated

values empty (ex. ',,110,' will only update the third value, advertising interval).
