I tested my new device under different region settings and have a strange behaviour.
When i change my settings, sometimes the wrong downlink frequency are used.
For example, i switched to asia settings with the following settings:
When i test the device with a confirmed message the uplink frequency is OK, but the downlink has the previously tested indian frequency:
Switching to another region and back to asia does not solve the issue.
Has anybody an idea what is wrong or have an idea for a workaround?
