Dear Friends,
now i am working with HC-12 for long distance data transmission. here i am facing some OTA problem for Upload the new program/sketch for my MC/arduino.
My project Concept:
i have a multi nodes for collecting temperature at different location. one master is collecting temperature data from all nodes and upload the data to server this main only connected with internet others are connected with only HC12. I set all nodes channels are different for avoid the data collision.
My task:
The above concept is working fine, but if i upload the new sketch like OTA is possible to master only other nodes can't because nodes don't have a internet connection. so i decide to upload the sketch via HC12 but HC-12 don't have a DTR pin for reset the node for set Boot loader for upload a sketch/ program.
If anybody have a idea or suggestion about this concept please let me know.
thank you
with regards
