Issue in using Simulated BLE Peripheral

[malikyaseen]

Hi
I have a scenario in which I am simulating a battery peripheral on an android device, using your tool for man in the middle attack and then connecting that peripheral using another android device using nrf connect. When gattacker is not used I am able to connect to the simulated peripheral while when using gattacker as MITM attack I am unable to connect to gattacker advertised peripheral. It just loads and does not connect.
I am using two linux virtual machines, device is cloned, initialized and notify is also working but with some default value which is not affected when it is changed from peripheral app
Kindly guide where i am missing something or doing wrong
I want to change values that are being transferred to receiving device

Peripheral Simulator app screenshot file, receiving device bluetooth log file (nrf connect app), terminal commands files are attached for reference. Advertisement and services files are also attached. Zip file was not being uploaded i had to rename bluetooth log file, advertisement and services files to txt files
