Before you start, make sure that your device was registered with Sigfox.
The following tutorials demonstrate how to register and get started with the SiPy. The board can be configured for operation in various countries based upon specified RCZ zones (see the
Sigfox class for more info). The SiPy, LoPy 4, and FiPy supports both uplink and downlink
Sigfox messages as well as device to device communication via its FSK Mode
from network import Sigfoximport socket# init Sigfox for RCZ1 (Europe)sigfox = Sigfox(mode=Sigfox.SIGFOX, rcz=Sigfox.RCZ1)# create a Sigfox sockets = socket.socket(socket.AF_SIGFOX, socket.SOCK_RAW)# make the socket blockings.setblocking(True)# configure it as uplink onlys.setsockopt(socket.SOL_SIGFOX, socket.SO_RX, False)# send some bytess.send(bytes([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]))
If your are experiencing issues with Sigfox connectivity, this could be due to the sequence number being out of sync. To prevent replay on the network, the Sigfox protocol uses sequence numbers. If there is a large difference between the sequence number sent by the device and the one expected by the backend, your message is dropped by the network.
You can use the
Disengage sequence number button on the device information or on the device type information page of the Sigfox backend to reset the number expected by the backend. If the sequence number of your next message is different from the last trashed sequence number, the message will be accepted.
Issues with the sequence number can occur when a lot of messages are sent when outside of Sigfox coverage for instance.
Firstly you will need to log into the Sigfox Backend, navigate to device, and click on the Sigfox ID of the affected SiPy.
You should now see the Information page with an entry
Device Type: followed by a link. Please follow the link
Finally, on this page click on
Disengage sequence number button in the upper right corner.
