"read timeout during skip" followed by "signal lost"

[reevolt]

Description

I have a heat pump Elco Aerotop S, connected it up to a recently purchased ebus adapter v5. The adapter is connected to a Raspberry pi 3. I installed the ebusd on the rasbperry, followed the entire checklist in the "getting starting" guide but I get an error message when the eBus is connected to the 2 wires bus.

I tried many options: connect the adapter via USB or using the GPIO, in standard mode or ehanced mode, the result is always the same. I tried to change latency settings with different values (20, 60, 20000) but the error still here. I also tried to remove the latency argument.

Also enabled debug level to have more info. Despite the different posts talking about this issue, I was not able to fix it.

There is a loop with these logs

[bus notice] signal acquired
[bus debug] ERR: read timeout during skip, switching to no signal
[bus error] signal lost
[bus notice] signal acquired
[bus debug] ERR: read timeout during skip, switching to no signal
[bus error] signal lost
....

Actual behavior

The error "signal lost" occurs after "read timeout error", regardless the value of the latency argument.

Expected behavior

Should not have a timeout error
