@robert-hh Thank you. I will work on that advice.

@Vercellotti a) You must set Putty to "No flow control", 8 N 1 b) Try to exchange RX/TX. (RX to Rx, TX to TX). The labeling is sometimes swapped. c) And yes, you do not need DTR.

@livius As previous I intend SiPy-1.6.7.b1.tar I can post you the entire code, but this could be used only with our device connected to the UART serial port. Anyway, I post you the code used to handle sockets, because I suspect that the issue could be related to this task: import _thread import tracingfunction import time import socket import pycom # Global array for rx data from serial port SerialRxPacketsLock = _thread.allocate_lock() # this value define the max number of parallel socket! # Don't configure a value grather than the maximum allowable connections # on uart device!! (see the define MAX_SOCK_NUM in the uart device project) MaxNumActiveSockets = 6 # this arry is used by the task serialport to request a close on the relative socket KillRequestSocketList = bytearray(MaxNumActiveSockets) # this mutex is used to avoid thread conflicts in th access of the list of packets and socket SocketListLock = _thread.allocate_lock() # list of packets that must be sent on a particular socket rxPacketsFromSerialPortList = [] # list of enabled sockets socketList = [] # list of id related to the socket! socketUniqueIdList = bytearray(MaxNumActiveSockets) pycom.heartbeat(False) currentRGBLed = 0x007f00 # this function return the number of current active sockets def GetNumOfActiveSocketList(): global SocketListLock global socketList global MaxNumActiveSockets idx=0 totalActiveSocket=0 SocketListLock.acquire() while(idx<MaxNumActiveSockets): if(socketList[idx]!=None): totalActiveSocket=totalActiveSocket + 1 idx = idx + 1 SocketListLock.release() return totalActiveSocket # this function return the position of the first free socket slot def ObtainSocketListPosition(): global SocketListLock global MaxNumActiveSockets idx=0 SocketListLock.acquire() while(idx<MaxNumActiveSockets): if(socketList[idx]==None): break idx = idx + 1 if(idx==MaxNumActiveSockets): idx=-1 SocketListLock.release() return idx def toggleRGBLed(): global currentRGBLed if(currentRGBLed==0x007f00): currentRGBLed=0 else: currentRGBLed=0x007f00 pycom.rgbled(currentRGBLed) # socketThread # This task is responsible to handle data from/to the socket # ------------------------------------------------------------------------------------------------------------------------------------------------------------------ # ------------------------------------------------------------------------------------------------------------------------------------------------------------------ # ------------------------------------------------------------------------------------------------------------------------------------------------------------------ def socketThread(voidPar): import stuffingfunctions global socketList global SerialRxPacketsLock global rxPacketsFromSerialPortList global KillRequestSocketList # we print on the terminal that the thread started print ("socketThread Started") # set counters and ids to zero idxSocketToCheck = 0 aliveCounter = 0 pycom.rgbled(0x00007f) # infinite loop!

@julian-cifuentes look here it is simple https://docs.pycom.io/pycom_esp32/library/machine.UART.html and connect RX and TX to pins like in datasheet https://docs.pycom.io/pycom_esp32/pycom_esp32/datasheets.html RX to TX TX to RX and GND

@jmarcelino created https://github.com/pycom/pycom-micropython-sigfox/issues/1 and also pull https://github.com/pycom/pycom-micropython-sigfox/pull/2

The latest firmware, 1.6.12.b1 has fixed this issue for machine.reset(). Typing CTRL-D in Pymakr still causes a crash but that is manageable by testing for machine.SOFT_RESET before attempting to set up Sigfox and if true, do a machine.reset() or machine.deepsleep(1) first.

@jcaron - I don't really have the facility to capture the actual Wifi messaging, but this may highlight the issue. I'm not using any other radios and primarily using and external antenna, but tried the internal too. The WDT in the boot.py seems to be working well - been running for 24 hours and keeps reporting - previously rarely got more than an hour. I can see the WDT kicking in and doing it's job. I guess this is the sort of thing the WDT was designed for!! Thanks for your help.

@jcleloup Yes, correct. The SiPy is not just a modem, it's also microcontroller and many times more powerful than the Arduino

@matt3526 DID anyone figure this out?

@jmarcelino There u go the WIFI Autoconnect was still on !!!!! Now it works. Thank you guys !!!!!!!

@VST-Admin The actual example in the in the examples section documentation mentions alarm.callback(None). The recent firmware supports the cancel method. So I recommend updating the firmware.

@souldrone Do not use Pymakr it is unsupported - wait for plugin arrival. Now use e.g. Arduino IDE -> COM port monitor or Putty to read/write UART repl.

similar problem. this: sigfox = Sigfox(mode=Sigfox.SIGFOX, rcz=Sigfox.RCZ1) s = socket.socket(socket.AF_SIGFOX, socket.SOCK_RAW) s.setblocking(True) s.setsockopt(socket.SOL_SIGFOX, socket.SO_RX, True) s.send(bytes([0x00, scale(lux.light()[0]), 3, 4, 5, 6, 7, 8, 9, 10, 0xAA, 0xFF])) retval = s.recv(32) print ("received " + retval) gives me: Traceback (most recent call last): File "<stdin>", line 164, in <module> OSError: [Errno 100] ENETDOWN whilst the backend shows me: Status : [ACKED] Data (Hexa) : cafecafecafecafe any idea what i'm missing here? It's definitively not the link - sender and receiver have free LOS. avgSnr=20.74 rssi=-52.00 Used HW: FiPy on '1.17.5.b6'

@livius Did a quick try. Got the following error: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/flash/lib/urequests.py", line 141, in urlopen File "/flash/lib/urequests.py", line 38, in __init__ OSError: -32512 Will look more into it later, but as fare as I can Google it might have something to do with the antenna transmission.

Take a look to an arduino like wrapper for pycom at https://github.com/dinosd/pyCom/blob/master/examples/arduino_sample.py import arduino estado = 0 estado2 = 0 cont = 0 A = 10 B = 11 C = 12 D = 13 E = 14 def setup(): arduino.pinMode(15, "ANALOG_INPUT") #PIN P15, there is no mode analog input in arduino but pycom needs it arduino.pinMode(8, "INPUT") # modes are "INPUT","OUTPUT","INPUT_PULLUP","INPUT_PULLDOWN","ANALOG_INPUT" arduino.pinMode(7, "INPUT") arduino.pinMode(A, "OUTPUT") arduino.pinMode(B, "OUTPUT") arduino.pinMode(C, "OUTPUT") arduino.pinMode(D, "OUTPUT") arduino.pinMode(E, "OUTPUT") def loop(): global estado, estado2, cont value = arduino.analogRead(13) millivolts = 1100 * value / 1.1 #max volts for analog in is 1.1V db = millivolts / 10 print(db, "DB") estado2 = arduino.digitalRead(8) if estado2: #this means high or you can write if estado2==1 estado = arduino.digitalRead(7) if estado: arduino.delay(500) cont += 1 if cont==1: arduino.digitalWrite(A, 1) arduino.digitalWrite(B, 1) arduino.digitalWrite(C, 1) arduino.digitalWrite(D, 1) arduino.digitalWrite(E, 1) setup() while True: loop()

Expansion board. Sry for late answers. Must wait 600s between different replies.

@livius said in sigfox payload formatting: @iotmaker you can simply convert it b=[int(x, 16) for x in payload] but question is how do you got this payload? on first you have '0x11' but on last '4e' without 0x ? That worked... did some modification and now we are good. thank you

Thanks to Livius. That worked!
