LoRa-MAC (Raw LoRa)

[Vicky_]

hello. I follow this tutorial to send data using LoRa MAC

I received this:

how can I get rid of the b'0.1'? I want 0.1 only because I am publishing this data to cloud.

I received this in cloud.

how to change this coding:

s.setblocking(False)
some_number = s.recv(64)
client.publish(topic=AIO_RANDOMS_FEED, msg=str(some_number))

Also I wanna ask how far it can goes? I searched but I cant find any documentation about the distance travel for LoRa-MAC.

Any help would be appreciated. Thanks!

@robert-hh Thanks! You saved my day again.

@vicky_ you can use decode to get ride of the b
b'0.1'.decode() gets '0.1", so you code would look like

s.setblocking(False)
some_number = s.recv(64)
client.publish(topic=AIO_RANDOMS_FEED, msg=some_number.decode())

The distance you can achieve with Raw LoRa is the same as with LoRa-MAC, because it is a property of the RF hardware. It all depends on proper RF design of your devices box, antennas in the mote and in your gateway. So, best case are a 5-10 km outdoors, fair case is about 3km, with a sound gateway antenna outdoors, no lower limit for the worst case.
