      Hi, In order to streamline our IOT equipment portfolio, I am seeking for a module that combines :
      1] ESP 32 with WiFi
      2] A mobile connection for MQTT (for example a SIM76 family)
      3] Two Serial ports available : Serial1 and Serial2

      This one looks great : IoT Base CatM but it seems that 1 Serial is used by the SIM module.
      The same appear to go for this module : Atom DTU NBIoT2

      Any suggestions how to combine a SIM76 family (or any other mobile chip), with the availability of Serial1 and Serial2?
      Thanks for your creativity.

        Hello @HappyUser

        ESP32P4 has 5 (five) UARTs. See here.

        AFAIK all other ESP32 variants only have 3 (three) or less UARTs. (Of which the first one is used for debugging.)

        BTW: are you aware of the fact that SIM76XXX is different from what is in IoT Base CatM (SIM7080G) and Atom DTU NBIoT2 (SIM7028)?

        • SIM76XXX uses LTE (which is different from NBIoT or LTE-M)
        • SIM7080G uses NBIoT or LTE-M
        • SIM7028 uses NBIoT only

        Thanks
        Felix
