Official bladeRF forum

My application involves using multiple bladeRFs at the same time. i want to transmit a given tone signal via a particular bladerf and other through 2nd Bladerf both connected on different usb ports of my laptop. i am using a single Osmocom Sink block and using Num Channels value as 2 to allow simultaneous operation of 2 bladerfs. However i am unable to comprehend the way GRC gives the id i-e [bladeRF sink] Using nuand LLC bladeRF #0 SN d543.. or [bladeRF sink] Using nuand LLC bladeRF #1 SN 3d83 to either bladerfs. the only part i am sure is that it is not dependent upon Serial number of bladerf. is it dependent upon the usb addresses or wat ? (ID changes as i switch between various usb ports)

Secondly can i direct a signal onto a particular bladerf using its serial number or any other such property, maybe through Device Arguments field etc in Osmocom Block ? if yes then How ?

Thanks in Advance ..
