Can not disconnect slave, need help

[ileon]

async fn main() -> Result<()> {
{
let mut ctx1 = get_ctx(&get_default_sp_builder(), 2)?;
let rsp1 = ctx1.read_holding_registers(1, 2).await?;
println!("{rsp1:?}");
ctx1.disconnect().await?;
}

let mut ctx2 = get_ctx(&get_default_sp_builder(), 1)?;
let rsp2 = ctx2.read_holding_registers(1, 2).await?;
println!("{rsp2:?}");
ctx2.disconnect().await?;

Ok(())

}

above is my code, the rsp1 is right, but failed at the ctx2 row
What is the right method? thanks!

Context? Fails how?

Context? Fails how?

there are two contexts, the ctx1 works normal, then the ctx1.disconnect().await? is not take effect, so the ctx2 panic because access is denied.

get_ctx() and get_default_sp_builder() are not provided by tokio-modbus and I cannot comment on this. Everything might happen behind the scenes.

Please re-open if you could provide a runnable or at least comprehensible example.
