The rx and tx pins are swapped for the bc95 vs the m35 module.
I'd suggest you update the firmware on the bc95 as well. This presents a challenge in that you need to solder some wires to the bc95 to a usb->serial converter. I use the usb base board for this. There's a windows program from quectel that does the firmware upload. You can also do this 'over the air', but I've not tried this.
