phy-as923-sub-region not applied ? #15522

Open rfuentess opened 3 months ago

Description of defect

In our mbed_app.json apply the following configuration: 

    "target_overrides": {
        "*": {
            ....
            "lora.phy": "AS923",
            "lora.phy-as923-sub-region": "AS2",
            ...
        },

By doing this, in theory we are setting AS923_LC1_FREQ, AS923_LC2__FREQ, AS923_LOWER_FREQ , AS923_UPPER_FREQ and AS923_RX_WND_2_FREQ to a proper range.

However, the first 4 defines are never used and AS923_RX_WND_2_FREQ is override later.

Still, I'm a rookie with Lora, so I'm not sure if mbed-os is using OK by trying to use the frequencies 923400000 and 923400000 for the RX1 and RX2 slots in both AS1 and AS2. However, based on what I understand from the lora regional specifications, I think no.
