I’m using RAK3172 chip as transmitter and RAK3172 evaluation board as receptor.
I can’t set both parameters as same.
AT+P2P=868000000:7:0:0:8:14 this is the parameter config in my chip using main controller. but can’t set the same parameter to evaluation board via Arduino, and its showing output as AT_ERROR. How solves this issue?
Thank you for the replay @carlrowan
I configured AT+P2P=868000000:7:125:0:8:14 this to rak3172 chip using esp32 main controller but it shows AT_PARAM_ERROR . so, can I conclude that at this moment I can’t move forward with two?
The AT_PARAM_ERROR means there are some parameter input that is not compatible to AT+P2P. Will there be a way for you to test the RAK3172 first directly and not via the ESP32 chip?
Do you have anything connected to pin 27 (GPIO12) of the RAK3172 that might pull the pin to GND?
This pin should be floating as it is used internally to detect whether the module is for high frequency or low frequency.
If you pull pin 27 to GND externally, the module thinks it is a low frequency module and rejects to use the upper frequency range.
Thanks for replay, * AT_BUSY_ERROR is returned if the device is configured to RX mode and still waiting for LoRa P2P packets.?
and also getting replay while send data using AT+PSEND, but not receiving in RX?
