Pi 5 stopping after 3 minutes and SDR in the wrong order

Issue with KrakenSDR RDF on iOS.

I rename m’y iPhone 15 pro max KrakenAndroid for the hotspot.

Use m’y iPad Air to connect to Raspberry pi hotspot krakensdr and I run KrakenSDR RDF from the iPad.

I create a collection file and start collecting, I get a bearing but it stop after about 3 minutes and the raspberry pi led go red.

I have to reboot to start again.

How could I fix to stop after 3 minutes?

I know location from the signal I am tracking,it show the at 180 degrees from the real location, could it be because the SN: are not in the good order?

Could I change the SN: to the correct order in the terminal?

The result of kraken_test

krakenrf@krakensdr: ~/krakensdr_doa

$

Also the pi 5 draw about 4watts and the Kraken draw 19-20 watts from the battery pack

The order of serial enumeration doesn’t matter, but for reference this order is normal.

For disconnection, after 3 minutes I can only guess that this sounds exactly like a power supply issue.

But the Kraken drawing 19-20 watts is clearly wrong. The Kraken runs at 5V 2.2A, so at most, it would draw 11W.

Can you try with another power supply first?
