Hi George: I had no end of trouble with the built-in bluetooth adapter on my laptop. It was an Intel adapter and would only work if I moved the target Zephyr box about 15ft away from the laptop. I cha

You didn’t check the return code from fs_open(). I am pretty sure the open failed, I think the correct file path is “/SD:/plink.csv”. You then tried to write to a file with an invalid handle which cau

Did you power up the Accelerometer? You should read the full datasheet, here is what is says about power: Operating modes The LSM6DS33 has three operating modes available:  only accelerometer active

Hi Edyta Your code doesn’t show what value you used for I2C_ADDR. You will not get an ACK on the I2C bus if you have the wrong I2C addr for the LSM3DS33. Without an ACK, you get a bus error. I think y

Hi Edyta: There are two ways to read sensors. If your sensor has a driver and you have set it up in the device tree correctly you can simply use the sensor examples. If your sensor is really simple, y

Thanks Charles. Bug #26939 filed…. Let me know if there is any other info I can provide. https://github.com/zephyrproject-rtos/zephyr/issues/26939 Lawrence King Principal Developer +1(416)627-7302

Hi Charles, I tried your suggestion, unfortunately it doesn’t help. Every dts that uses mcumgr, also has the console on the same port, there is no existing board that routes the mcumgr to a different

Dear All: I am trying to setup mcumgr to allow code download over a serial port and use the shell. In this case I have 2 serial ports in play. The first serial port is where printk() sends messages. I

Hi Charles: This just my personal opinion on the subject. Two approvals is the right thing to do and what the TSC approved earlier this year. BUT, if the second +1 is just a rubber stamp approval of t

Hi Patrice: Your statement that the behavior of the LED is ‘inverted’ is completely correct. Your statement about the current is at best confusing. It is true that the GPIO doesn’t need to ‘source’ th

Hi Martin: Excellent, thank you. The bit I missed was the correct syntax for /delete-node/ I put the following 3 lines just before &flash0 /delete-node/ &slot0_partition; /delete-node/ &slot1_partitio

Dear all: I am trying to change the partition table from the default as defined in the board file inside Zephyr to a slightly different configuration. Obviously I could do this by editing the file in

Excellent solution. Thank you. Lawrence King Principal Developer +1(416)627-7302

I have a little problem with the device tree In zephyrproject/zephyr/boards/arm/nrf52840_mdk/nrf52840_mdk.dts the uart is defined as: &uart0 { compatible = "nordic,nrf-uart"; current-speed = <115200>;

Hi Brian: You can always test the value of the GPIO with gpio_pin_read() in the callback, if it is 1, then the cause is a rising edge, and if it is 0 the cause was a falling edge. Unfortunately if the

Dear All: I have a similar problem to what Frank Viren is seeing in his thread “bt_gatt_notify multiple characteristics”. How to determine the pointer to the right characteristic. When my central conn

Hello: I am not sure if this issue should be asked here, or in the MCUBoot mailing list, but I will start by asking here. I want to change the partitions in my nrf52840, this is easy when building a z

I think you need a few more things turned on in your config file. To figure out what you need turned on I always use the menuconfig tool and diff the old and new .config files, then I take the changes

Hi Marti: Thanks, setting the udev rules did the trick. Just so other people know what to do: $ sudo cp ${HOME}/opt/zephyr-sdk/sysroots/x86_64-pokysdk-linux/usr/share/openocd/contrib/60-openocd.rules
