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

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

Which one is it? "uart0" or "cdc_acm_uart0"?

Can you please share your build-folder/zephyr/zephyr.dts file?

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

Could you share an example of a working scenario and a non-working scenario?

 

Kind regards,

Håkon

To have the same confifuration as me you can take the bluettooth shell sample with the dongle BLE nrf52840 dts, i use the exactly same configuration.

  Using Bluetooth Shell

With the sample you can scan device and connect to it as a central device in BLE. When youa re conencted you can discover services and subscribe to one caracteristic. I modify the sample to be able to subscribe to more notification. I subsribe to curstome services witch send accelerometer data, pressure...ect. these data are send at 10HZ for 6 of them and one is send at 50Hz.
i try to receive all theses data. When i receive a data i print it with printf or with printk. But the speed of print is more lent than the n umber of data that i receive. I tried to increase the speed of uart0 to be able to print more data but i loss many data, is it possible to print more faster the data that i receive ?

If i receive less data i succed to print them all (it's the working scenario) but i need to print more data.

Is it more clear ?

Kind regards,

Hi,

 

As the zephyr/tests/bluetooth/shell sample can be configured in many ways, can you please answer these questions so that I'm able to fully understand how you've setup the sample?
