The ESP32 DW3000 Pair is unable to Connect

[JerryIeong]

Hi,

Let me thank in advance.

I am trying to connect two ESP32 DW3000 and to show the distance between two by using the sample code in arduino "ex_06a_ss_twr_initiator" and "ex_06a_ss_twr_responder".

However, the connection is not successful, once I embedded the programmes into the baords and open the serial monitor to see the result, the program just showed

• SS TWR INIT v1.0
• DEVICE ID: deca0302
• XTRIM OTP READ FAIL
• PLL is locked..
• PGF cal complete..

(The board name I used is ESP32 Wrover Modulus)

Did I miss something and can anyone help me out with this?

Thank you for your helps!
