Hi Karel,
I apologise for the confusion. The easiest way to differentiate which ttyUSBx (port) corresponds with the Span and the Dock is to use the command motelist. In regards to your second question it is best practice to use them. They can normally be purchased from standard medical suppliers such as this http://bio-medical.com/products/electrodes.html.

First, I noticed several errors or imprecision on the Shimmer User Manual (Rev2Rd): - Source code for HelloWorld (modify "boot ready" to "bool ready" in module HelloWorldC and COMPONENT=TestBluetoothAppC to COMPONENT=HelloWorldAppC in Makefile) - In the section 5.5.2, there are some problem with permission (we have to use the "sudo bash" command at the beginning) - Same section, it is really not clear which node is supposed to be bootstrapped (span or shimmer sensor): same ttyUSB0 used for every command - ./zattach -v -n /dev/ttyUSB0 should be replaced, I guess, by ./zattach -v -n /dev/ttyUSB1 Secondly, we plan to use ECG and EMG sensors and I saw on the YouTube tutorial that they use a sort of stickers to attach the electrodes. I would like to know where we can find this type of equipment or if we can just use tape or adhesive bandage without disturbing the measures. Thank you in advance for your help.
