read error when trying to pull RTE and capacity

[lorenzoooooo]

I am using openups with firmware 1.9 and the configuration set is in the attached file.

While trying to run the following code inside GetStatus() method of object HIDOpenups:
" ret = sendMessage(OPENUPS_CLOCK_OUT, 0);
usleep(1000);
recvMessage(recv);
parseMessage(recv);
"
I get the following error:
"
hid_interrupt_read failed with return code -110
Read error [0xc0]: -110
"
it reads the capacity and the RTE but puts to 0 all the other values.
If I comment this part of code I get all the values with correct values except for the RTE and capacity and the error is not present.
Furthermore I saw that the windows interface doesn't have this problem.

Will this EVER get fixed?

It seems that I have got it working reliably by removing all delays and sending the OPENUPS_CLOCK_OUT message twice. In particular, I changed GetStatus into this:

void HIDOpenUPS::GetStatus() 
{
    unsigned char recv[32];
    int ret;

    sendMessage(OPENUPS_GET_ALL_VALUES, 0);
    recvMessage(recv);
    parseMessage(recv);

    ret = sendMessage(OPENUPS_GET_ALL_VALUES_2, 0);
    recvMessage(recv);
    parseMessage(recv);

    ret = sendMessage(OPENUPS_CLOCK_OUT, 0);
    recvMessage(recv);
    parseMessage(recv);

    ret = sendMessage(OPENUPS_CLOCK_OUT, 0);
    recvMessage(recv);
    parseMessage(recv);
}

This is on a little rpi zero w, running Raspbian GNU/Linux 11 (bullseye). I was having the same problem as you described it above.
