Multi-threaded data transfer #426

Closed bolahg closed 3 years ago

bolahg commented 3 years ago

I need to transmit data on the same channel at the same time. How can this be implemented. For example, with the nRF24L01 cards, you can organize a multithreaded connection in 6 channels. I need the same thing, but with the lora libraries

AFAIK, no wireless chips and wired chips can "truly" send multiple packets in the same time.

You think it so as the bandwidth of the chip is fast enough and there is capability of re -transmission.

You need to finish transmitting a packet before sending another one.

The bandwidth of LoRa is low. The time to send (Time-on-air) is around few milliseconds to few seconds depending on the settings of LoRa chip.

Moreover, SX1278 is half-duplex. You can't send while receiving and vice versa.
