### LoRa/Sigfox FCC/CE/RCM Certification Scripts
2+
3+
This directory contains script(s) that should be executed when the board boots, preparing it for the lab tests.
4+
5+
When beginning a test, after the board has been powered up (either for Sigfox or LoRa), the first thing is to call one of these functions:
6+
7+
```
8+
start_test_fcc()
9+
10+
start_test_rcm()
11+
12+
start_test_ce()
13+
```
14+
15+
####To begin test:
16+
17+
For Sigfox only these functions are used:
18+
19+
```
20+
do_freq_hopping_fcc()
21+
22+
do_freq_hopping_rcm()
23+
24+
do_freq_hopping_ce()
25+
26+
do_continuos_transmit(<frequency>)
27+
```
28+
29+
For LoRa these are the functions to use:
30+
31+
```
32+
select_new_frequency():
33+
34+
sock_send_repeat(packt_len,num_packts,
35+
delay_secs,
36+
fhss=False)
37+
38+
sock_send_all_channels(packt_len,delay_secs=0.1)
39+
```
40+
41+
_Both LoRa and Sigfox can also use the normal socket functions to send single messages during testing._
