Hi,
I want to display my measurements for a few seconds after I took them and then send a uplink to the NS.
I have tried a few things and seems not anything from Dr. Google.
I cant seem to find the correct way to call the display.
Your help will be appriciated.

SH1107Wire display(0x3c, 500000, SDA, SCL ,GEOMETRY_128_64,GPIO10); // addr, freq, sda, scl, resolution, rst
/*
* set LoraWan_RGB to Active,the RGB active in loraWan
* RGB red means sending;
* RGB purple means joined done;
* RGB blue means RxWindow1;
