Hi,
I am using Lora RAK3172 for my project,
Can we send JSON string using AT command as AT+PSEND={“device”:“RAK3172”,“status”:“active”} ?

No.
AT+PSEND

<payload>: 2…500 digit length, must be an even number of digits and characters 0-9, a-f, A-F only, representing 1…256 hexadecimal numbers.

Example to send 0x11, 0x22, 0x33:

AT+PSEND=112233
OK
+EVT:TXP2P DONE

Dear Bernd,

I am attempting to establish P2P communication between three devices, but both the transmitter and receiver are receiving garbage values. I am sending data as a JSON-converted string and receiving it in the same format.

Could you please assist me in troubleshooting this issue? I have attached the relevant code files for your reference.

Thank you for your time and assistance.

Sincerely,
Rushikesh
