Hello there,
Thank you for your question.
Unfortunately changing the default PIN is not possible in the current FW version of the sensor, this feature should be available in the upcoming FW updates.
Enabling/disabling transmitting can only be done through the FM device, but not within the sensor itself. Please read more about EYE beacon sensors on our Wiki page https://wiki.teltonika-gps.com/view/EYE_SENSOR_/_BTSMP1
If you have more questions please reach out to us via VIP Helpdesk or contact your sales manager/distributor.
