[Replicant] Exposure Notification not working

[Nick]

Hi,

I want to use the national app that my government recently made 
available that uses the Exposure Notification system to alert me of 
people I've been in contact with who turn out to have been 
infectious.

I found that the microG project have implemented this in their 
alternative to Google Play Services, which is great. However, after 
installing it, and then installing the exposure notification app 
from my country (NHS Covid-19 app), the Exposure Notification check 
seems to fail. Could this be due to Replicant not supporting BLE (I 
have no idea if it does)?  I installed the bluetooth firmware on my 
phone (i9300) specially, so at least basic bluetooth is active.

Thanks for any advice or pointers! Has anyone else got an app using 
exposure notification working? I was originally trying to get Google 
Play Services to work for this, which is proprietary, and was very 
happy to find that microG should be able to do the job. So it's 
frustrating to seemingly fall at the last hurdle.
