BLE_Health_Thermometer for mbed HRM1017 with BLE library 0.1.0
Release 0.1.2: Minor bugfix release.
2014-09-02, by Rohit Grover [Tue, 02 Sep 2014 17:01:18 +0100] rev 60
Release 0.1.2: Minor bugfix release.
Bugfixes
~~~~~~~~
- drop un-necessary app_button.c.
Compatibility
~~~~~~~~~~~~~
Compatible with revision 0.1.0 of the BLE_API.
Release 0.1.1
2014-09-02, by Rohit Grover [Tue, 02 Sep 2014 16:42:56 +0100] rev 59
Release 0.1.1
=============
Minor bugfix release.
Bugfixes
~~~~~~~~
- drop duplicate app_timer.cpp; it's already present in the mbed SDK.
- add missing code for custom_add_in_descriptor() to custom_helper.cpp
Compatibility
~~~~~~~~~~~~~
Compatible with revision 0.1.0 of the BLE_API.
Release 0.1.0
2014-09-02, by Rohit Grover [Tue, 02 Sep 2014 16:15:26 +0100] rev 58
Release 0.1.0
=============
We've achieved significant gains in power consumption: the BLE_Beacon demo now
runs at around 35uA of average current broadcasting once a second at 0dB; when
not using the radio, this demo consumes around 7uA.
Features
~~~~~~~~
- Replace initialization of high-frequency external crystal clock-source with
the use of low-frequency clock. This brings in significant gains in power
consumption.
- Re-implement the micro-second timer on nRF51 using the app_timer module
(which internally uses RTC). This limits the precision of the us_Timer to
30uS; but brings in significant gains in power consumption.
- Reduce the number of available app_timers and the event depths for app-timer
events; this will reduce memory consumption for zero-initialized data by
around 1K.i
- Remove the call to conn_params_init() at startup. This is not mandatory; and
was causing an unnecessary re-negotiation of connection parameters a few
seconds into every connection.
- Reduce default transmission power level to 0dbB (was 4dbB before).
- Reduce min connection interval to 50ms and max to 500ms (previous values
were much larger).
- Replace a few instances of use of wait() with nrf_delay_us().
- onConnection() callback now receives connection-parameters applicable to the
new connection.
- onDataSent() callback now receives a count parameter containing the number of
times notifications were sent out since the last callback.
- A 'reason' parameter has been added to Gap::disconnect() to indicate the
reason for disconnection; and also to the onDisconnection callback to
receive a reason from the remote host.
- disable the app_gpiote module by default.
Bugfixes
~~~~~~~~
- onDataWritten() callback now passes an additional parameter
(GattServer::WriteEventCallback_t) encapsulating the update. This avoids
having to re-fetch the updated characteristic's value attribute. It also
fixes a bug where multiple updates to the characteristic's value-attribute
could get clobbered if they occurred in quick succession before the
callbacks could be processed.
Compatibility
~~~~~~~~~~~~~
Compatible with revision 0.1.0 of the BLE_API.
