BLE 4.0 USB dongle does not discover BLE 4.1 peripheral (CYBLE-022001-00)
This problem does not involve any Cypress Kits or the programming/configuration of the BLE 4.1 device. I have scoured the forums but found nothing that might answer this.
I have a sealed third-party BLE device which apparently uses the EZ BLE part number CYBLE-022001-00 which is supposed to be BLE 4.1 compliant, yet when it is advertizing I am unable to discover it under Windows 7 with several different BLE 4.0 USB dongles (eg. CSR 8510). Also it is not discovered by and Android 4.3 phone (Galaxy S3). However it can be discovered by a Toshiba Satellite laptop (integral BLE 4.0) and most newish Android phones and iPhone 5. I know the BLE 4.0 USB dongles on the Win7 PC are working because they can discover the Android 4.3 phone and the Toshiba Satellite laptop BLE.
I was under the impression that BLE 4.0 (Smart ready) and BLE 4.1 are compatible, so should be able to discover each other when made discoverable. Why can't a BLE 4.0 USB dongle discover the CYBLE-022001-00 BLE 4.1 device?
