[CDC ACM] Is it possible to run CBOR mode on CDC ACM ?

[jalinei]

Hi !

Today I was playing with thingset, trying to have a cdc acm running with serial mode in binary mode.
I could not figure it out.

This is my overlay :

/ {
	chosen {
		zephyr,console = &cdc_acm_uart0;
        thingset,serial = &cdc_acm_uart1;
		thingset,can = &fdcan2;
	};
};

zephyr_udc0: &usb {
	pinctrl-0 = <&usb_dm_pa11 &usb_dp_pa12>;
	pinctrl-names = "default";
	status = "okay";
	cdc_acm_uart0: cdc_acm_uart0 {
		compatible = "zephyr,cdc-acm-uart";
	};
    cdc_acm_uart1: cdc_acm_uart1 {
		compatible = "zephyr,cdc-acm-uart";
	};
};

My .conf

CONFIG_SERIAL=y

CONFIG_THINGSET=y
CONFIG_THINGSET_SDK=y
CONFIG_THINGSET_SERIAL=y
CONFIG_THINGSET_TEXT_MODE=n


CONFIG_THINGSET_SUBSET_LIVE_METRICS=n

I'm testing by doing :

echo -ne '\x05\x81\x05' > /dev/ttyACM1 
cat /dev/ttyACM1 | hexdump -C

No luck so far. Am I missing something ?
