WARNING!
MicroPython code stored in flash is saved in the file system as

. If the
file system has not been formatted, then the following error is generated:
OSError: [Errno 7019] ENODEV
The file system can be formatted in one of three ways:
In XCTU by using the

Example code on the coordinator module
The following example code forms an 802.15.4 network as a coordinator, performs a network
discovery to find the remote node, and continuously prints out any incoming data.
1. Access the MicroPython environment.
2. Copy the following sample code:
print("Forming a new 802.15.4 network as a coordinator...")
xbee.atcmd("NI", "Coordinator")
network_settings = {"CE": 1, "A2": 4, "CH": 0x13, "MY": 0xFFFF, "ID": 0x3332,
"EE": 0}
for command, value in network_settings.items():
xbee.atcmd(command, value)
xbee.atcmd("AC")
# Apply changes
time.sleep(1)
while network_status() != 0:
time.sleep(0.1)
print("Network Established\n")
print("Waiting for a remote node to join...")
node_list = []
while len(node_list) == 0:
# Perform a network discovery until the remote joins
node_list = list(xbee.discover())
print("Remote node found, transmitting data")
for node in node_list:
dest_addr = node['sender_eui64'] # using 64-bit addressing
dest_node_id = node['node_id']
payload_data = "Hello, " + dest_n "!"
print("Sending \"{}\" to {}".format(payload_data, hex(dest_addr)))
xbee.transmit(dest_addr, payload_data)
# Start the receive loop
print("Receiving data...")
print("Hit CTRL+C to cancel")
while True:
