Allow setting to arbitrary byte arrays by preceding the string with 0x
for things like
meshtastic --setchan psk 0x1a1a1a1a2b2b2b2b1a1a1a1a2b2b2b2b1a1a1a1a2b2b2b2b1a1a1a1a2b2b2b2b --info
Example usage:
Or to configure an ESP32 based board to join a wifi network as a station (wifi support in the device code is coming soon):
```
meshtastic --set wifi_ap_mode false --setstr wifi_ssid mywifissid --setstr wifi_password mywifipsw
```
Or to configure an ESP32 to run as a Wifi access point:
```
meshtastic --set wifi_ap_mode true --setstr wifi_ssid mywifissid --setstr wifi_password mywifipsw
```
Use this method for the --settime command line flag - which sets the device
time to be the same as the local computers time (in UTC)
def sendPosition(self, latitude=0.0, longitude=0.0, altitude=0, timeSec=0, destinationId=BROADCAST_ADDR, wantAck=False, wantResponse=False):
"""
Send a position packet to some other node (normally a broadcast)
Also, the device software will notice this packet and use it to automatically set its notion of
the local position.
If timeSec is not specified (recommended), we will use the local machine time.
"""
