Scans all eight 2.4Ghz channels and reports noise values. These can be used to select a suitable channel.
The 2.4GHz receiver will be blocked for about 2 seconds. In this period it is not possible to receive any transponder data. Do not call this command during normal timing operation!

[Noise] | 00 = no noise |
A channel with more than >50% noise is not recommended to be used.
Example:
← SITESURVEY\n
→ SITESURVEY;00\n
→ 00;02\n
→ 01;00\n
→ 02;02\n
→ 03;03\n
→ 04;07\n
→ 05;09\n
→ 06;0a\n
→ 07;04\n
→ \n
You should select the second channel (note that there is a -1 offset in internal channel numbering)
Note: You can always read the noise level of the current channel by calling BEACONGET
