Access to SLPI_QUP6_UART while voxl-px4 is running
-
Hello,
I have a VOXL2 to which I need to connect two extra sensors that communicate using serial.
One of the sensors (barcode reader) which I connected to /dev/ttyHS1 using the VOXL 2 USB3.0 / UART Expansion Adapter is already working.
The problem is where to connect the second sensor (LIDAR), since we tried to connect it to the J19 QUP6 UART, that worked but only if the voxl-px4 is not running, as stated by your documentation.
Since we wont use any GPS is there anyway to be able to read the data from the sensor using the libqrb5165-io even when voxl-px4 is running?
Is there any other serial port available?
Thank you. -

Thank you.@madswamp , currently the DSP where PX4 runs can only load one application, for example PX4 or the libqrb5165-io UART bridge. It is not possible to run them concurrently even if you do not use the particular UART port in PX4.
Is it possible for you to use a serial to USB adapter and plug it into the USB 3.0 port (on the expansion adapter) and the other end into your Lidar?

@Alex-Kushleyev, yes, we will do just that, connect a USB Hub to the USB 3.0 Port and connect it to the Hub, that way we still have the USB available for the WiFi and other possible sensors.
Thank you for your response.
