Removes the channel from the specified
index
. On the 868MHz band the channels 0 to 2
cannot be removed, they can only be replaced by other channels using the lora.add_channel
method. A way to remove all channels except for one is to add the same channel, 3 times on
indexes 0, 1 and 2. An example can be seen below:
lora.remove_channel()
On the 915MHz band there are no restrictions around this.
lora.mac()
Returns a byte object with the 8-Byte MAC address of the LoRa radio.
lora.callback(trigger, handler=None, arg=None)
Specify a callback handler for the LoRa radio. The
trigger
types are
LoRa.RX_PACKET_EVENT, LoRa.TX_PACKET_EVENT and LoRa.TX_FAILED_EVENT
The LoRa.RX_PACKET_EVENT event is raised for every received packet. The
LoRa.TX_PACKET_EVENT event is raised as soon as the packet transmission cycle ends,
which includes the end of the receive windows (even if a downlink is received, the
LoRa.TX_PACKET_EVENT will come last). In the case of non-confirmed transmissions, this
will occur at the end of the receive windows, but, in the case of confirmed transmissions, this
event will only be raised if the
ack
is received. If the
ack
is not received
LoRa.TX_FAILED_EVENT will be raised after the number of
tx_retries
configured have
been performed.
An example of how this callback functions can be seen the in method lora.events().
lora.ischannel_free(rssi_threshold)
This method is used to check for radio activity on the current LoRa channel, and if the
rssi
of the measured activity is lower than the
rssi_threshold
given, the return value will be
True
, otherwise
False
. Example:
lora.ischannel_free( -100 )
lora.set_battery_level(level)
Set the battery level value that will be sent when the LoRaWAN MAC command that
retrieves the battery level is received. This command is sent by the network and handled
automatically by the LoRaWAN stack. The values should be according to the LoRaWAN
specification:
5.2.2.4 LoRa
