0
means that the end-device is connected to an external power source.
1..254
specifies the battery level, 1 being at minimum and 254 being at maximum.
255
means that the end-device was not able to measure the battery level.
lora.set_battery_level( 127 ) # 50% battery
lora.events()
This method returns a value with bits sets (if any) indicating the events that have triggered
the callback. Please note that by calling this function the internal events registry is cleared
automatically, therefore calling it immediately for a second time will most likely return a value
of 0.
Example:
def lora_cb (lora) :
events = lora.events()
if events & LoRa.RX_PACKET_EVENT:
print( 'Lora packet received' )
if events & LoRa.TX_PACKET_EVENT:
print( 'Lora packet sent' )
lora.callback(trigger=(LoRa.RX_PACKET_EVENT | LoRa.TX_PACKET_EVENT), handler=lora_cb)
lora.nvram_save()
Save the LoRaWAN state (joined status, network keys, packet counters, etc) in non-volatile
memory in order to be able to restore the state when coming out of deepsleep or a power
cycle.
lora.nvram_save()
lora.nvram_restore()
Restore the LoRaWAN state (joined status, network keys, packet counters, etc) from non-
volatile memory. State must have been previously stored with a call to
nvram_save
before
entering deepsleep. This is useful to be able to send a LoRaWAN message immediately
after coming out of deepsleep without having to join the network again. This can only be
used if the current region matches the one saved.
