Pygate packet forwarder ERROR

[Charles Westhoff]

Hi,

I'm installing a Pygate/Gpy, firmware 1.20.2.RC10 and registered it at TTN. Apparently it got a connection, but it was last seen 11 days ago. I'm not using the LTE part for coms, only WLAN.

(sysname='GPy', nodename='GPy', release='1.20.2.rc10', version='v1.11-b2436d4 on 2020-07-01', machine='GPy with ESP32', pybytes='1.5.0', pygate='1.0.1')

main.py

from network import WLAN
import time
import machine
from machine import RTC
import pycom

pycom.heartbeat(False)

def machine_cb (arg):
evt = machine.events()
if (evt & machine.PYGATE_START_EVT):
pycom.rgbled(0x103300)
elif (evt & machine.PYGATE_ERROR_EVT):
pycom.rgbled(0x331000)
elif (evt & machine.PYGATE_STOP_EVT):
pycom.rgbled(0x000000)

machine.callback(trigger = (machine.PYGATE_START_EVT | machine.PYGATE_STOP_EVT | machine.PYGATE_ERROR_EVT), handler=machine_cb)

wlan = WLAN(mode=WLAN.STA)
wlan.connect(ssid='xxxxxx', auth=(WLAN.WPA2, "xxxxxx"))

while not wlan.isconnected():
time.sleep(1)

print("Wifi Connection established")

rtc = RTC()
rtc.ntp_sync(server="0.pool.ntp.org")

fp = open('/flash/config.json','r')
buf = fp.read()

machine.pygate_init(buf)

Atom Console after firing up:

...

The End

Then the LED goes RED.
When looking at other Pygate issues I don't see ERROR's in the packet forwarder.

Please advice, what is happening here ?

Hi,
Ive seen this issue before.. It was cleared after I reflashed my GPy and clearing the 'CONFIG', 'NVS' and partitions (and I clicked 'erase during update' as well) in the Pycom Firmware update tool. I believe it has to do with using other timers in previous configurations

The error line is here:

[106664086] lorapf: ERROR [main] impossible to create Timer Sync thread (12) (34) (11,22,1)

Let me know if that worked for you!

Hi Gijs,

Thanks, that did the trick. I've used the GPy for earlier projects, so maybe that was messing up the installation. Maybe a good idea to add these advanced settings to the instructions.

The LED is GREEN now. Thanks Gijs

@Gijs Thanks!! This solved my problem!

for anybody else running into this - pretty sure it's about the memory consumption as explained here: https://docs.pycom.io/tutorials/expansionboards/pygate/#setup
