I want to set up the RAK2247 SPI + USB with mPCIe interface into an x86 system. From all the examples a RPi or similar SBC is being used. Has anyone tried using the RAK2247 or RAK833 in an x86 system?
I am trying to set up a simple PoC, two x86 systems and have one receive data while one transmits. I have on my system Ubuntu 1604 kernel 4.4, lsusb shows me the FTDI device.

[ 9.583850] usb 1-5: FTDI USB Serial Device converter now attached to ttyUSB1
I can access the serial port but in the documentation there’s no reference to the communication protocol (baud rate, flow control, etc). There are no command set as well.
Has anyone else tried something similar to this? Will the command set for RAK833/RAK2247 be published? Is what I am trying to accomplish feasible with this product?
I have the RAK2247 installed into our system, which has mPCIe interface with only USB 3.0 signalling. When calling lsusb I am able to see the UART FTDI device.
Not too sure what happened there, left device idle. Don’t believe it is related.

Okay. So, re-installed OS, then followed instructions again. Seems like it is working now. I will need to modify the address from router.us.thethings.network apparently…
ERROR: [up] getaddrinfo on address router.us.thethings.network (PORT 1700) returned Temporary failure in name resolution
On TTN, its recommending ttn-router-us-west. What do I need to do to implement this change?
Hi @hfung
Did you change something in global_conf.json?
The “url” is router.us.thethings.network . ttn-router-us-west is load balancer for this region, not address.
So, I’m back to my original predicament… what I am seeing now, again, is:
ERROR: Failed to load fw 1
ERROR: Version of calibration firmware not expected, actual:0 expected:2
ERROR: [main] failed to start the concentrator
Since I am having the USB mPCIe SKU - are the following signal required?
