CC2340R2: Bluetooth 5.3 without RTOS

Part Number: CC2340R2
Other Parts Discussed in Thread: LP-EM-CC2340R5, CC2340R5

Tool/software:

I am working on project that requires sensing 10 sensors (through SPI, I2C and ADC) and sends the data to the mobile application via BLE 5.3 protocol. I thought of using LP-EM-CC2340R5 evaluation board which have 36KB of SRAM. But, upon compilation of the example from Simple Link SDK in RTOS folder called "basic_ble" this example itself occupies 31.3KB (i.e. 85%).

I thought of removing RTOS so that the SRAM consumption will be reduced. But I don't see any BLE examples in nortos folder of Simple Link SDK. My questions are

1)Do you have any examples of BLE transmission without rtos?

        -if no whether BLE 5.3 stack is compatible enough to be developed without using any OS

    Hello Ruthrapathy,

    Thanks for reaching out. Correct, Bluetooth LE examples require RTOS to work. You can take a look the propRf examples (not Bluetooth LE protocol) inside the SDK: \examples\nortos\LP_EM_CC2340R5\prop_rf.

    BR,

    David.
