Revision: RM502QAEAAR13A02M4G
Using auto-selected MBN profile “Commercial-TMO” is blocking outgoing UDP packets with a 0 checksum, which are still valid UDP packets per spec.
Using MBN profile “ROW_Generic_3GPP_PTCRB_GCF” allows the UDP packs but doesn’t seem to support 5GSA on TMobile and the connection isn’t as stable. I can also move the sim card to an Inseego M2000 hotspot with 5G and it also allows the UDP packets.
Is there a setting I can change on the modem to allow the checksum 0 UDP packets with Commercial-TMO profile?
