messages from BTLE GATT server truncated at 20 bytes

All messages from a BTLE GATT server are truncated at 20 bytes.

The server can be tested against a different client and the full payload is visible (in my case 150 bytes).

This issue is reported by other users as well (see https://forums.garmin.com/developer/connect-iq/f/q-a/196823/bluetooth-low-energy-mtu-size-for-characteristics)

As 20 bytes is the default MTU size, I guess this bug might be MTU size related.

    I'm affected by this too. Can not get more than the first 20 bytes of any Characteristic from my continuous blood glucose monitor. That's barely past the header data. I am supposed to get 363 bytes and only get 3 messages of 20 bytes each instead of 121 each...
