Dear Teltonika,
we are working on Teltonika TFT100 device. I ask you if you can resolve a doubt that came to us when testing the Bluetooth communication with the device: from the documentation we realized that there is a call to obtain the value of a certain IO with "eBT_PT_GetIoValue", but we have not found any function that allows you to set the value of an IO using only the Bluetooth connection. So we wondered if it was possible to do this, and with what call, or if it wasn't implemented at all.
Regards
