What config changes I need to make for running the Modbus Example on nRF52832?

[cipher52]

Hi everyone,

I am working with nRF52832, I am trying to implement the Zephyr Modbus client example onto it, but i keep receiving the following errors.

*** Booting nRF Connect SDK d96769faceca ***
[00:00:00.270,385] <err> modbus_serial: Failed to configure UART
[00:00:00.270,385] <err> modbus: Failed to init MODBUS over serial line
[00:00:00.270,416] <err> mbc_sample: Modbus RTU client initialization failed

There is this Thread that says that the issue is in the config. Can someone tell me what changes I need to make for the application to work.

Regards

Cipher

Hi,

Did you try enabling parity? You can do this through the app.overlay. E.g.,

 

&arduino_serial {
	status = "okay";
	parity = "even";

	modbus0 {
		compatible = "zephyr,modbus-serial";
		status = "okay";
		de-gpios = <&arduino_header 15 GPIO_ACTIVE_LOW>;	/* D9 */
	};
};
