Hi Dave, I think you could try to look into selecting root command feature. Create dummy command with only “login” subcommand. Set this dummy command during system startup (shell_set_root_command(“dum

Hello, I'm quite new to Zephyr, so I may have missed this, but I can't seem to find an easy way to add a simple password protection wall for the shell commands. I don't need or expect a full user mode

@Lawrence King Thank you for the code! @All I tried the last few days to get it working but I don’t know how to use a second UART. I’m using the nRF52832dk board which has only “uart0” defined in the

I have used the Longan module with Zephyr on nrf52840. I connected it to a Serial, then modified the Longan library to compile and work under Zephyr. This isn’t everything you need (missing the .h inc

Hi all, I’m new to zephyr and need some help. I have a nrf52dk board and want to use this ( https://www.longan-labs.cc/1030001.html ) serial to CAN device. I was able to test this with an Arduino and

Dear all, if somebody tumbles here with google about the parity, i found no way to do it from device tree, but 8-databits, even parity, 1 stopbit seems to work in my case with patch pasted below. Ther

Hello all, I have been doing development with stm32f103 (blue-pill) board - and it has the system bootloader burned in. The bootloader uses settings 115200, 1 stop, even parity [1]. I would like to ch

There's a "Group Reply" button in the bottom right-corner. It took me while to find because you can see it only *after* clicking "Reply", that's an unusual interface.

Hello Johan, Thank you for your response. Following your suggestion I've updated my kernel to 4.20 and there is a change in behavior though I don't see LE CODED scanning to be working + btmgmt behavio

Hi, HCI_Read_Local_Extended_Features is a BR/EDR-only command, which is why you are getting this response from the LE-only controller. You’ll also see that it’s not listed in the supported commands re

Hi, Notice that these are MGMT commands and events, i.e. just communication between BlueZ user space and the Linux kernel and not directly related to the controller. The Set PHY Configuration MGMT com

Thank you Rodrigo, I'll work on the code you shared with me and I'll let you know the results.

Based on the documentation uart_poll_in returns zero to indicate a character arrived. A negative value, which you're checking for in your code, would indicate the operation failed. Chances are it's wo

You have to enable uart interrupt at the conf files.
