Syncing the clocks of Lora/Pymeshed Devices

[boda]

I am building a testing series of meshed devices that are listening for Bluetooth Beacon advertisements. But I need to sync the clock of the nodes to get accurate measurements. Is there any way I can do something like this using PyCom's libraries? Thanks!

For reference, "PainlessMesh" is a wifi-meshing library that syncs the node(s) clocks: https://gitlab.com/painlessMesh/painlessMesh/blob/master/examples/startHere/startHere.ino

@oligauc Thank you!

@boda Please find example code below on how the sync clock.

from machine import RTC
from network import WLAN
import machine

wlan = WLAN(mode=WLAN.STA)
wlan.connect('your ssid', auth=(None, 'your pass'))
while not wlan.isconnected():
    machine.idle()
print('WiFi connected')

rtc = machine.RTC()
rtc.ntp_sync('pool.ntp.org', update_period=3600)

while not rtc.synced():
    machine.idle()

print("RTC NTP sync complete")
print(rtc.now())
