if wifiCfg.is_connected():
ticks_ms = time.ticks_ms()
if time.ticks_diff(ticks_ms, old_tick) > 40000:
old_tick = ticks_ms
try:
req = urequests.get("http://api.m5stack.com:5003/timer-cam/image?tok=xxxxxxxxxYOUR-TOKENxxxxxxxxx&width=320&high=240&decode=png")
if (req.status_code) == 200:
print("Len: " + str(len(req.content)))
img_dsc = lv.img_dsc_t({
