Hi,
I have successfully built and ran the MQTT sample (/opt/nordic/ncs/v2.7.0/nrf/samples/net/mqtt) on the nRF9160-DK. I did have a few problems with SIM coverage and firmware versions which was sorted in this ticket.
MQTT Sample Not Connecting on nRF9160 Board
I would now like to move this code onto my own board.
When I run this code on my own board, I see this error.
*** Booting nRF Connect SDK v2.7.0-5cb85570ca43 ***

};

/* Enable uart1 for tracing. */
&uart1 {
status = "okay";

pinctrl-0 = <&uart1_default>;
pinctrl-1 = <&uart1_sleep>;
pinctrl-names = "default", "sleep";
};
/ {
chosen {
nordic,modem-trace-uart = &uart1;
};
};
I use UART0 for my serial terminal.
Would appreciate your pointers on this,
Thanks,
Rod
