Bluetooth Mesh stack
Simple Architecture
• Free RTOS not required (code example available)
• BLE stack schedule thanks to a dedicated state machine
• Application do not require any resource manager (stack and application running on same core)
• Automatic efficient power (sleep mode) management
• RF HW block is not preempting any system (MIPS, peripherals) resources to process RF activities (advertising,
connected events)
• BLE events (connect, disconnect) handle over basic SW interrupts
Application simplicity

43. BlueNRG-LP
BLE HW resources - autonomous
The BueNRG FSM engine provide all needed resources to sustain
BLE advertising & connection without preempting any Core resources
The BLE stack need to be schedule (ModulesTick) to poll HW registers and check if
any incoming data are available (events or data)
A too long execution within the App_Tick processing, delaying ble stack scheduling
will so not impact the RF link however however will lead to latency (missing data,
events)
