Low SNR and RSSI after update Mbed on mDot

Hello all!

Something strange happen after i update Mbed version to the latest. I’ve got very poor SNR and RSSI. And also i’ve updated the LoRaServer app/gateway, but i think that not the problem. See this image, when i’m using old version of mbed and new. What could go wrong? The gateway and mDot are close.


Best regards
