I need to connect my CC3200 Launchpad to IoT Hub from Energia. I followed a tutorial: https://github.com/farukc/AzureIoTHub-TI-CC3200, but this one is using CodeComposer which is not available for Mac OS. I run the CC3200 project in Energia, but on Serial Monitor Terminal I received a weird coded message:
zÒrZzXBH(úXX{ÿFRBXþÂ#ÞXJJ,
and I have no idea what's going on.
The Serial Monitor baud must be set on
115200 baud
. This change fixed my problem.

I'm developing a script that permits to connect to the internet through a Mediatek MT7612U wifi adapter (Alfa AWUS036ACM) and making some connection tests using speedtest-cli, iperf3 ...
My script is running under OpenWrt linux system. I installed Openwrt in a raspberry PI4 Model B. I plugged to the raspberry two wifi adapter (Alfa AWUS036ACM with Mediatek MT7612U chipset).
The script is running permenantly, and making periodically some connection Tests. After a period of time I lost the connection.
When I checked the system log I found this error reported by the kernel:
kern.err kernel: [ 1929.020945] mt76x2u 2-1:1.0: error: mt76x02u_mcu_wait_resp failed with -110
The issue disappear when I reboot the system. But I need to fix it without rebooting.
I tried to reset the usb device with ioctl USBDEVFS_RESET but that caused the lost of corresponding network interfaces,
I tried also to poweroff/poweron the usb device with commands like that:
echo disabled > /sys/bus/usb/devices/usb2/power/wakeup
echo enabled > /sys/bus/usb/devices/usb2/power/wakeup
but the issue is not fixed
I tried also to unbind/bind the usb device
echo '2-1' > /sys/bus/usb/drivers/usb/unbind
echo '2-1' > /sys/bus/usb/drivers/usb/bind
and the issue is not fixed also
Has someone an idea why I got this blocker issue. Is there an idea to fix or bypass it without the need to reboot the system.
I've also been getting this exact issue. I've also been using the Alfa AWUS036ACM.
I've tried unplugging the adapter and that resets it, then after putting it into monitor mode again it works for a short while before failing with the issue OP has again. I'm using a Raspberry Pi 3b
We have device ""FT245R USB FIFO" USB to Seriel for communication from Windows 10 using D2xx driver.
FT_OpenEx() API works without any issue. But whenever user unplug/plug new USB device(Mass storage device) , during that time FT_OpenEx() API failed to execute, so handle invalid and our data communication interepted. Could you let us know what can I do further to resolve this issue ?
Note: I have opened handle using following command FT_OpenEx("FT245R USB FIFO", FT_OPEN_BY_DESCRIPTION, &handle), I open it everytime, whenever I need to talk with communication device. tried with seriel number of the device , but still communication fails when unplug/plug other USB device.
I have Raspberry Pi 3 model B
OS: Raspbian(jessie)
I want to create a connection from my smartphone to a headless raspberry, and connect the headless raspberry to a network(which the smartphone is conencted).
like the vacum cleaner robot (IRobot) or Web camera which has an app, or any device that needs an initial connection to setup it's network.
the initial connection needs to be from a remote device, mainly a smartphone app.
What did i try:
1. bluetooth - i've managed to setup the bluetooth in the raspberry. when i try to connect, a popup appears on the raspberry which ask to confirm connection, because the raspberrry needs to be headless, this option is not good for us.
if i set the bluetooth as follow: sudo hciconfig hci0 sspmode 0
when i try to connect to the raspberry, a popup appears in the smartphone required a PIN code, this option may be good, if i new the PIN code.
2. P2P - i try use wifi direct from my smartphone
i've create file called p2p.conf inside /etc/wap_supplicant
inside this file i wrote the following:
ctrl_interface/var/run/wpa_supplicant
update_config=1
device_name=raspberry
device_type=1-0050F204-1
driver_param=use_p2p_group_interface=1
p2p_go_intent=1
p2p_go_ht40=1
then stop the wpa_supplicant and change
sudo wpa_supplicant -B -iwlan0 -Dnl80211 -c/etc/p2p.conf
i've started wpa_cli
and then p2p_find
it's started scanning
when i search from the smartphone for the raspberry, i found the raspberry, when i try to conenct it asks me for PIN code, the PIN code is showen in the raspberry wpa_cli.
two problem i have from this option:
1. the network needs to be connected.
2. the PIN code changes, and i can't make it fixed.
Is there a way to make an initial connection to setup a network from the smartphone to a headless raspberry?
I have problem with communication via USB CDC with Windows. On Linux or Mac everything work good.
So, when I try to connect to my COM port I get notification from PUTTY "Unable to open communication to COM2. Unable to configure port.
It is my own device based on Rx63n uC, I transmit in FullSpeed standard, packet in size less than 64 bytes. I'm used 2 endpoints for bulk transfer IN/OUT.
In USBLyzer I got information thatSTALL packet is received from my device after error (USBD_STATUS_CANCELED).
I used driver from Windows 10 usbser.sys.
Any ideas what is wrong?
I forgot to add that in USBLyzer I see a lot of my packets, and after transferred some data it generate error as above.
I have connected a PiCAN2 board with raspberry pi running latest Jessie. When I try to send some CAN messages to my PC ( PC is connected via a USB to DB9 CAN interface to the PiCAN2 board) through this PiCAN2 using the can-utils, it runs into ERROR-PASSIVE state as soon as I bring the CAN interface up. But, when I enable loopback mode, I am able to send messages and receive them using two different terminal window on the raspberry pi itself. I enabled loopback mode using
sudo /sbin/ip link set can0 type can bitrate 500000 loopback on.
Can some one tell me more about the loopback mode? I want to make sure that my hardware setup for PiCAN2 is correct. Is it possible to confirm that my CAN board is configured correctly because I can send/receive messages using loopback mode?Or this doesn't necessarily mean that it is correct?
I also want to know why I get the ERROR PASSIVE mode - does it indicate that the PiCAN2 is not configured correctly OR does it mean that my USB to DB9 CAN interface has some problem? I am new to this area and any help would be nice. Thank you.
