Which example from the IoT SDK do you use? Do you have made any modifications to it? What is the chip version of the nRF51 chip that you are using? (What is printed on the chip?) Did you also add the dependencies listed in this post? devzone.nordicsemi.com/.../

There may be another problem with the hardware Arch BLE, because it has only 16kB RAM which is not enough for IoT SDK.

Hi!

Maybe i am wrong, but based on your previous screenshot and Glenn's one, it "almost" looks like you are trying to connect to his dongle (probably just same vendor)! So i believe that this is not coincidence but wrong MAC address. Please ensure that address comes from nRF51 device. You can call:hcitool lescan on your RaspberryPi for that purpose.

Does your BLE usb dongle enumerate?

Quickly check if "hciconfig" lists it up. You could also verify if it is BLE enabled by running "hcitool lescan". This should list all devices advertising nearby.

If it enumerates, when you run the command "connect xx:xx:xx:xx:xx 1", verify if it connects to the device or not by checking "hcitool con".

Alternativly, you could do a normal connect to the device by issuing "hcitool lecc xx:xx:xx:xx:xx:xx". This is just a litmus test for bluetooth connection (ipv6 connection is not established using this command).

In addition to connecting to a device, there are a couple of other steps that you have to do, please take a look at this post.

Which commands do you run in order to connect? Before connecting, you should run the following commands:

 # Mount debugfs file system
 sudo mount -t debugfs none /sys/kernel/debug
    
 sudo echo 35 > /sys/kernel/debug/bluetooth/6lowpan_psm

 sudo sysctl net.ipv6.conf.all.forwarding=1

 sudo echo "connect AA:BB:CC:DD:EE:FF 1" > /sys/kernel/debug/bluetooth/6lowpan_control
