It’s not Bluetooth. Bluetooth is a local protocol and not something anyone can block by region. Used to connect to local devices but Airsense 11 is not one them. If it was only Bluetooth, you could connect but the provider nor the manufacturer could connect unless they went through your smart device.
My Airsense 11 does not show up in my Bluetooth list.
It is a cellular connection to enable world-wide. But that can be blocked by governments and filtered by IP regions by the manufacturer. Don’t know if ResMed is doing that. But like Sleepster said, some Airsense 11 have 4g modem and some none. There was a chip shortage that force some to not have the modem. My USA DME provider told me that and that I was lucky to have a modem.
So either you have a Airsense 11 that did not have a modem chip or maybe your area does not have 4g and it cannot connect.
I don’t think they changed the software so the menu would not show if you have a modem or not. If it does not, it will just not connect.
FYI: Even those of use with modems and connections, use the SD card daily to get data to OSCAR. OSCAR is great! MyAir is not worth looking at unless you are happy with summary data only.
I think it is only useful for those that have compliance requirements. So, it helps organizations tracking your use and summary numbers. Nothing to help you customize your treatment.
Did I say “OSCAR is great!”
