Hi,
I've setup a central device and peripheral device. If I put the devices close then the central device can read signal of rssi around -45dBm but if I take the devices further from each other, then the Central device can see the peripheral device with a maximum signal strength of -79dBm, not beyond that. However if I read the Peripheral rssi value on the CySmart App then I can see it goes beyond -79dBm. I can see it goes up to -93dBm.
I am reading the field "advReport->rssi" from the CYBLE_EVT_GAPC_SCAN_PROGRESS_RESULT event of AppCallBack method.
Could someone please clarify? Am I missing something in the BLE component or code?
Thanks.
Kind regards,
Jitender

This is a limitation of PSoC BLE 4.1 devices, the RSSI value returned saturates at -79dBm. Anything beyond will be reported as -79dBm only.
