@peat_psuwit do you have a spec for the Thai EBS? Looks like they require a working SIM card?
I still maintain that we'll need a CB topic database from e.g. Android and should not not rely on hardcoded set of topics from a non-regional specification.
In theory we should only need the table from 9.4.1.2.2 of 3GPP TS 23.041.
Unfortunately, the test today is inconclusive on whether we need to explicitly subscribe to topic "4370" or not.
We don't already? According to the same table, 4370 is not supposed to be settable by the user and always subscribed (I'm kind of extending the 3GPP definition of MMI here) so this shouldn't be a question - since afaik it's not required to be implemented at modem level, we should check what ofono reports and subscribe to the missing ones.
buuuut we did figure out that Pebbles work fine on focal, the issue is in the RockWork app and it would need a reimplementation - probably less work for me to add Pebble support to mine once it actually exists.
Though if it syncs with WiFi a lot of the functionality might not be possible without an account and the official app. Sniffing BT
