Detailed Description

Design desisions:

• The radio interrupt has highes priority
• The radio ISR is triggered by the radio DISABLED event.
• The radio is either disabled by receiving and transmitting, or by the receive timeout timer, that triggers the DISABLE task of the radio, if the reception timed out.
• The ancor of every timing, is the reception of the first PDU in a connection event.
• During advertising, the accuracy of the ancor is not important, as there is already some random jitter to be applied to the interval according to the specs.
• CC[ 0 ] of timer0 is used to start the radio
• CC[ 1 ] is used to implement the timeout timer and DISABLES the radio
• CC[ 2 ] is used to capture the anchor when receiving a connect request or the first PDU in a connection event.
• RTC0 is always running and used as time base. TIMER0 is just started if the RTC0 comes close to a connection / advertising event.

Resources used:

• The radio peripheral is exclusively used by Bluetoe.
• Timer0 is exclusively used by Bluetoe.
• Timer1 is used by Bluetoe, if the synchronized_connection_event_callback<> feature is used.
• Bluetoe will switch the HFXO on and off.
• RTC0 is exclusively used by Bluetoe.
• Bluetoe will switch on the configured low frequency clock source.
• CCM, AES, and RNG peripheral are exclusively used by Bluetoe, if encryption is enabled.
• The highest priority interrupt level is exclusively used by Bluetoe.
• Bluetoe used PPI channel 19 exclusively
• Bluetoe used PPI channel 18 exclusively, if the synchronized_connection_event_callback<> feature is used.
