Class A LoRa communication

[lora master]

Hello,

I would like to have a possibility to send data from the sensor and then leverage the fact that I operate class A device and receive data from the gateway and currently I am trying to understand better this functionality… so I am wondering:

1) are tx and rx operate on different frequencies? I am asking as in many cases I can see:

mac set rx2 3 869525000 (while lora works on 868)

2) can I apply some logic to feedback stream / e.g. if sensor will send number 1, I will send back value 2? My understanding is that logic needs to be applied on application server (as number 1 will be encrypted during transmission and only decrypted when received by the app server via gateway/network server). I am wondering if processing delay might impact the behavior of such simple two-way communication (e.g. do I need to send value 2 back to sensor during next transmission)?

3) what would be an example of code that does transmit and then receive data, For example:
radio tx 48656c6C6F
radio rx <something>
I am wondering how to make it effectively and accordingly to the standard.

Thank you!
