Information about what is written in the custom FW
RUI API Version: 3.2.6
Firmware Version: RUI_4.0.5_RAK3172-E
AT Command Version: 1.5.10
I am creating a system that returns the receiving side’s RSSI and SNR to the sending side when received.
Disclose the source of the incoming custom FW.
Currently, the sending side is prepared using the teraterm macro. (Rak customization is not used separately)
I am running the above system.
The problem is
Set the receiving side using AT command (RAK_SERIAL_PORT_TOOL_V1.2.1.exe)
The above sender macro also
When I corrected this and changed the sf, there was no response at all.
Custom FW initial settings
uint16_t sf = 7;
It is well known that if you write with sf = 7, it will work.
I’ve looked at a lot of things, but I still don’t understand the problem with custom FW.
