Cheap Bluetooth or Wi-Fi sticks sold under many labels. Torque Pro and Car Scanner usually connect; extended, hybrid, and UDS requests often fail on clones. Typical products: unnamed Amazon “ELM327” dongles, Veepeak OBDCheck, BAFX, Konnwei, and ANCEL units marked ELM. Judge by chip quality, not the printed brand.
