I am currently working on a project, where I need to send data from first unit to the second unit which is a few km apart, so I decided to go with hc-12 RF module as it covers upto 5km. Then the data received in the second unit is again to be transmitted to the last unit which is several km apart from each other, so I decided to go with sx-1278 RF module which can easily transmit data up to 30kms. I am trying to get the received data to print on the serial monitor. So, how do I transmit the received HC-12 data in the second unit using the sx-1278 RF module to the third unit? Is this operation even possible? Are these two boards compatible with each other?
If the answer is yes, please do help me out with the coding part on how to interface these two RF-modules.
Thanks in advance
