Kerlink GW: Bluethooth connection

Hi There,

Well I know I am asking a silly question to you all. But I want to know the answer from you all.
why Kerlink GW isn’t having Bluetooth facility. if suppose, we have to upgrade software on the gateway but there is some issue of USB port, Local, debug port. then how can we transfer the software file toward the device.

In brief, let me tell you condition,

My device at the top of the tower, currently it is not working (as per our application). now there is only one chance to get live is software reconfiguration. but USB, Local, Debug port is faulty then how can reconfigure the device.

thanks,
