Cannot modify the configuration with downlink messages

[bienvuinfo]

TrackerD 1.4.4, TTN network V3

Clearing ALARM with the downlink payload 0x02 01 works well as expected.

Unfortunately no other configuration parameter is actually changed with a downlink payload f.ex:

0x01 00 01 2C // Same as AT+TDC=300000
0x03 00 01 2C // Same as AT+MTDC=3000000
0xAE 00 // Same as AT+LON=0
0xA5 01 00 00 // Same as AT+SMOD=1,0,0

The download messages are well received and decoded by the node.

I checked what is the problem and I will fix it in the latest version V.1.4.5
