Now it’s the asynchronous open that’s causing trouble. That *should* be blocking. The program should not continue until the URC arrives. I will need to test that more.

Anyway, another change in TinyGSM:

    // Use an asynchronous open to reduce the number of terminal freeze-ups
    // This is still blocking until the URC arrives
    // The SARA-R410M-02B with firmware revisions prior to L0.0.00.00.05.08
    // has a nasty habit of locking up when opening a socket, especially if
    // the cellular service is poor.
    // NOT supported on SARA-R404M / SARA-R410M-01B
    // sendAT(GF("+USOCO="), *mux, ",\"", host, "\",", port, ",1");  <-----------------------------  Comment out this section
    // waitResponse(timeout_ms, GF(GSM_NL "+UUSOCO: "));
    // stream.readStringUntil(',').toInt();  // skip repeated mux
    // int connection_status = stream.readStringUntil('\n').toInt();
    // return (0 == connection_status);

    // use synchronous open  <-----------------------------  Enable this section
    sendAT(GF("+USOCO="), *mux, ",\"", host, "\",", port, ",0");
    int rsp = waitResponse(timeout_ms);
    return (1 == rsp);

sendAT(GF("+USOCO="), *mux, ",\"", host, "\",", port, ",0");

int rsp = waitResponse(timeout_ms);

return (1 == rsp);
