Good day. Thank you for your question.
You may test with a breathalyzer (alcohol sensor) that has BLE function. The BLE functionality allows our devices to configure custom sensors to work with our devices, provided those BLE sensors advertise data packets that can be captured, saved, and sent to the server where they can be parsed. Also, we do have Mercury C4 Breathanalyzer protocols implemented but it is only available on FMC125/FMB125/FMM125/FMU125 since it is connected via RS232.
