Hi Leo, great test results you’ve got there, have you by any chance done a distance test to see how far off the tow nodes can still communicate?

The Distance was impacted by some different factors, like coding, TX_PWR, antenna gain, to balance the transmit speed (latency) and distance, here is the 915M, OQPSK-SIN-250 coding (Chip antenna) test result, it's can stable at around 80 meters, the stable means it's has the >90 Packet Error Rate (PER). But this distance was an Extreme distance, with no object between the sender/receiver. Possibly I do not suggest using such a long distance for real application. But if using an external antenna with 3dbm gain, then the distance will be much more Credible. image image
