Gravity Module not working with PHY Coded

Dear community,

We are finding a couple of limitations on configuring your device that you may help us to solve: https://wiki.dfrobot.com/SKU_TEL0149_Gravity_BLE_Sensor_Beacon

We are trying to configure your Gravity module to broadcast data on PHY Coded without success. 

Even more, we detected that in the release notes of your NanoBeaconConfigTool, it states that:

v3.3.3

1.       By default, disable 125K PHY

Why is that the case? How to enable?

The module emits data with our configuration when configured on Legacy mode (LE 1M).

Thanks in advance!
