Hi CRUSTY,
I have not yet measured the detailed communication distance, just experimented in my house.
What antennas are used for Tx and Rx?
What is the critical communication distance?
Also, what is the RSSI value at that time?
I have the wio-SX1262 linked below which does not have the 30-pin connector implemented. If you read the post and replies in the last part of the wiki, there is a link to the drawing.
The SX1262 datasheet is available here
“14.6.2 Application Design of the SX1262 with RF Switch” would be helpful.
[EDIT]
I haven’t looked into this in detail yet, but perhaps the RF_SW pin needs to be controlled by XIAO.
[EDIT]
To put the RF switch in receive mode, add the following to the receive side sketch.
#define RF_SW D5 // RF_SW HIGH:Rx, LOW:default
pinMode(RF_SW, OUTPUT); // RF_SW
digitalWrite(RF_SW, HIGH); // Receive mode
