BLE DFU fails after a certain time

Question

Hi, When I try to update the firmware by sending 20 bytes at a time, it fails after around 1.25 minutes consistently. 1. Is it because nrf52 cannot hold the ble connection beyond 1.25 minutes? I can see the led status change on the nrf52 dev board as if it has lost connection. 2. How do I increase this time in secure bootloader ble code? I'm using SDK 15.2. 3. How do I increase the NRF_SDH_BLE_GAP_DATA_LENGTH to 244? Besides making changes in the sdk_config.h are there any more changes to be made? After I change NRF_SDH_BLE_GAP_DATA_LENGTH = 244, for the last execute command I receive 60-04-08 in response. Also for all data objects, I have to use this size command - 01 02 00 10 00 00. I was trying to make each data object of the size 3904 bytes as it is divisible by 244 (BLE packet size).
