Baudrate serial with Dongle BLE nrf52840

[Piwy]

Hi,

I use a dongle BLE nrf52840 with a software Bluetooth shell from NCS 2.0.
I use this dongle with this sample as a central device, i connect it to peripheral and receive 6 notifications at 10Hz and one more at 50Hz.
I use a socket to be connected to my dongle BLE with my PC.
To be able to save all my data i used to play with the serial baudrate.

1 ) Is it ok to configure baudrate with Uart_line_ctrl_set ?

2) Is it possible to configure Buadrate to 1M or even more (4M) for transmission ?

If it's possible, how to configure it ?

If it's not , is there another way to have all my datas ?

Regards,

Pierre-Yves

i have this configuration : in my ovverlay:

 

       
       &zephyr_udc0 {
              cdc_acm_uart0: cdc_acm_uart0 {
                     compatible = "zephyr,cdc-acm-uart";
                     label = "CDC_ACM_0";
              };
       };
       

And i tried to put uart0 to 1M :

&uart0 {
	compatible = "nordic,nrf-uarte";
	status = "okay";
	current-speed = <1000000>;// <115200>;
	pinctrl-0 = <&uart0_default>;
	pinctrl-1 = <&uart0_sleep>;
	pinctrl-names = "default", "sleep";
};

Here we have the current-speed i spoke about. I'm i correct when i say that this is the monitor speed of the shell command interface ?

Can you please share the full overlay file, and your build-folder\zephyr\zephyr.dts file?

Are you pointing zephyr,console and zephyr,shell to uart0 or cdc_acm_uart0?

 

Kind regards,

Håkon

as i say before i have many data that i receive with notification on my shell interface, but when i want to retrieve all the datas, i loss some of them, is it possible to increase the speed  of transmission, diplay ?
Maybe i don't explain verywell i'm sorry, told me if it's not clear

[Piwy]

yes like i say i use shell bluetooth sample, i use the same configuration as this sample of zephyr

There is also the same overlay in shell-module sample and in all the sample with shell commands
