RMT error while trying to read a ds18b20 ow sensor that is not connected

[bpop2000]

Expected behavior

I can capture the error of a ds18b20 ow sensor that is not connected and I expect no other error messages in the console

Actual behavior

With the ds18b20 sensor disconnected, there are bursts of RMT RX errors in the console. This is not always visible but arrives in intervals. This is tested with an idx v3.3-beta2 build from the #Nodemcu custom build page.

Test code

Provide a Minimal, Complete, and Verifiable example which will reproduce the problem.

temp_pin = 27

readtemp(temp_pin) -- read ds18b20

main_timer = tmr.create()
main_timer:alarm(10000, tmr.ALARM_AUTO, function()
readtemp(temp_pin) -- read ds18b20
end)

t = require("ds18b20")
send_idx = { [27] = 127, [21] = 128, [22] = 129}

function readout(temp)
  local amb_t = ""

  for addr, temp in pairs(temp) do
--    amb_t = string.gsub(temp,"%.", "") * 1    -- convert to integer
    amb_t = tonumber(string.format("%.1f", temp)) -- float version
  end

  if amb_t ~= "" then
    if debug == 1 then print ('Temp: '..amb_t) end
    Send(send_idx[temp_pin], amb_t)
  else
    local txt = Host.."_ds18b20_fout:_"..amb_t.."_"
    if debug == 1 then print (txt) end
    Send(269, txt)
  end
end

function readtemp()
  t.sens={}
  t:readTemp(readout, temp_pin)                      -- use address in flash
end
