I made the Bluetooth(hm-10) app that transmitt temperature, illuminance, humidity data to smartphone  
with thunkable.  
but thunkable can’t read the data that bluetooth(hm-10) provided

I tested bluetooth with ble terminal and bluetooth worked fine.  
here is images and app link i made

Glad this got solved! It looks like you changed to the service UUID. We also see this work sometimes if you change **0000ffe0** to **0000ffe1** and vise-versa.
