Reach RS and LoRa 868/915 MHz radio

I took another shot at interrogating the radio for its settings and got something back this time.
*Edit:

I was using ascii this whole time then in the documentation it explicitly says its hex.
I used RealTerm set up the Baud rate to 9600

I sent the interrogation/read command (0xFF 0x4C 0xCF 0x52 0xA1 0x52 0xF0) and got this:

```
 		  HEX(responce)		       Meaning
```
```
Preamble:   24			            None
```
```
Model Name: 31 30 31 48		        101H
```

FW version:	31 36 31 30 30 34 31 	1610041

```
LoRa MAC:	A3 6C 7D 03 00 39 00 71 
```

Group ID:	00 			            None (I thought this would have been the propriatary "key")

```
RF Freq:    0D F6 38 		       915MHz
```
```
RF Tx Rate:	05 			           18.23Kbps
```
```
RF Power:	07 			           20dBm
```
```
UART Baud Rate:	06 			       57600bps
```
```
UART Parity:	00 			        None
```
```
Wakeup Time:	05 			        1sec
```
```
End Word:	21 			            None
```

It is curious even though I set the baud rate to 9600bps the radio claims to be talking back at 57600bps.
No, I dont get anything back when I change the baud rate to 57600.
Maybe this is a change in the firmware that did not get documented in the Design Guide.

Thats it for today.
