Thanks Jason,
I will try the new firmware and give you know the results.
Exactly, AT&V no reply every time.
For ATI I get:
MultiTech xDot
Firmware : 3.0.0-rc7-mbed144
Library  : 3.0.0-mbed144
MTS-Lora : 3.0.0
OK
I get nothing. Connected via UART.
By the way, I have two set of models xDot MTXDOT-EU1 (EU868) and xDot MTXDOT-NA1 (US915). With US915 Model I have no problems with interaction.
Hi Steve,
I see the following types of packets received from xDot: DnCnf, UpCnf, JnAcc, and JnReq.
Best Regards
Thank you, Jason, for your prompt reply.
I use the statistics command (CommandTerminal :: Dot () -> getStats ();) to see the number of Up Packets.
The following structure describes the statistics data. And I see that the Up field has 32 bits (4 bytes):
        typedef struct {
                uint32_t Up;
                uint32_t Down;
                uint32_t Joins;
                uint32_t JoinFails;
                uint32_t MissedAcks;
                uint32_t CRCErrors;
        } mdot_stats;
