I have upgraded device (WIPY2.0
) from1.7.2.b1
to1.9.2.b2
and have problems:- ntp_sync most of the time not wrok (hang and never ending)
i use for it old method
def getNTPTime(host = "pool.ntp.org"): port = 123 buf = 1024 address = socket.getaddrinfo(host, port)[0][-1] msg = '\x1b' + 47 * '\0' msg = msg.encode() TIME1970 = 2208988800 # 1970-01-01 00:00:00 # connect to server client = socket.socket(AF_INET, SOCK_DGRAM) client.setblocking(15) client.sendto(msg, address) msg, address = client.recvfrom(buf) t = struct.unpack("!12I", msg)[10] t -= TIME1970 tuple_time = time.localtime(t) rtc.init((tuple_time)) client.close()
but also tested if
rtc.ntp_sync
could help but same result :(- i2c not work - i2c buss error
i init it with id=0 (i do not remember if in 1.7.2 it was hardware or software based)
bus=I2C(0, I2C.MASTER, baudrate=100000, pins=("P19", "P20"))
to test it what is going on i have updated board 3 times (all times sucessfully)
but with the same result
i have downgraded firmware back to 1.7.2.b1
all work without any problems - any hint?

Hello
I try this firmware and the exemple of nano Lora gateway and TTN
https://github.com/pycom/pycom-libraries/tree/master/examples/lorawan-nano-gatewayIt's OK for Uplink messages with ABP node.
But with Downlink message (APB node) and join reponse (OTAA), I have this error for every incomming UDP message on the gateway from TTN.
--> Downlink timestamp error!, t_us: 4294606989Thanks
