How can I test the lora driver？

[kp339]

Hi, I just cross compile the driver and install successful, if I type "ifconfig" cmd I can found the wpan0 site like this
`[root@TW-G01] /mnt/sda1/twiot/ko/lora# ifconfig

How can I test the communication between two devices? Can anyone tell me the steps to use the test application? Thanks!

I will follow the test application's README file and have a try, thanks!

Hi, I just follow the README file and have a try, but the socket always bind failed, here is the log:

Do anyone have the same problem with me？How can I solve this problem?
Thanks！

fe80::2946:df2b:4cd8:5dc5/64 is a Link-local IPv6 address. According to IPv6 spec, you have to assign it to the interface.

Here is the example. You can refer to page 76 of the slide https://www.slideshare.net/chienhungpan/lets-have-an-ieee-802154-over-lora-linux-device-driver-for-iot
