LP-CC1352P7: BLE Scanner

Part Number: LP-CC1352P7
Other Parts Discussed in Thread: CC2650

i have an LP-CC1352P7-4 development board and a CC2650. The CC2650 is connected to an OLED display, and I can send images using my phone, and they are displayed on the OLED, working fine. Now, I need to scan the CC2650 device and send an image from the LP-CC1352P7-4 development board. However, in the simple Central SDK, it's not able to show its own TI-based BLE device; it shows TI BLE device after a few scans. I've tried all settings, but it gives me the same result. The CC2650 is advertising every 5 seconds, and the LP-CC1352P7-4 scans for 10 seconds.

Give me some suggestions related to BLE gateways.

    Hi Vishal,

    I'm not sure what you mean when you say "it's not able to show its own TI-based BLE device; it shows TI BLE device after a few scans".

    Are you scanning in a busy environment? Per default, simple central will only scan until it gets 8 results, then stop. Maybe you should increase this value? It's set in simple_central.h:

    // Maximum number of scan results.
// Note: this value cannot be greater than the number of items reserved in
// scMenuConnect (See simple_central_menu.c)
// This cannot exceed 27 (two-button menu's constraint)
#define DEFAULT_MAX_SCAN_RES                 8

    You could also consider adding some filtering in order to only get the desired scan result.

    Cheers,

    Marie H
