CC2745R10-Q1: Variation in syscfg settings and RCL GPIO Output

Part Number: CC2745R10-Q1
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

I have a CC2745 as BLE Central, a CC2340 as BLE Peripheral.
I'm using simplelink_lowpower_f3_sdk_8_40_02_01, basic_ble example code.

When I update the BLE Device Role to Central in syscfg, Configurations for both Central and Observer are seen. (Refer refer attached sysconfig).
Is this expected ?

I had enabled RCL on both CC2745, CC2340
I see CC2745 is starting with observer mode configuration at boot(100ms interval), not sending out connection requests even though advertisement are being sent from CC2340
but after sometime switches to central mode(30ms interval).

I want to know if the analysis -> 'starting with observer then switching to central' is right ?
a. If so, what should be done to avoid this role switch
b. If not, why does RCL RF GPIO Signals are placed 100ms apart, than the expected 30ms ?

    Hello,

    The difference between the scan settings is that Observer Configuration is for general scanning parameters. Central scan parameters are for when initiating connections. Initiator scan settings (Central configuration) are different than general scan settings (Observer configuration).

    Hope that helps.

    Best,
