Yes, it can work as an observer. You can view the Advertisement packets received by the BLE dongle using the CySmart API.
Cypress provided libraries to build your own app as well, to obatin the data sniffed by the dongle.
The libraries are available with the CY8CKIT-042-BLE Package available on our website.
And is it possible to use the CySmart USB Dongle to sniff packets of an unencrypted BLE connection? I.e. the packets that flow between a peripheral and a central that have an established connection.
Bump! Would love to hear an answer on this as well.
@martin.roa.villescas_1981691 - did you find any solution for this?
This does seem to be an important tool that Cypress is missing.
