Question about Error Codes - Meaning/Frequency

[Timmmy001]

I have Questions which codes are of concern and in which frequency are negligible: With 26815 readings (with 24 reading every 10 sec. / approx 17h long) I get 33 errors each code 4 (timeout?). I use HardwareSerial on a ESP32.

Stupid question, but is this a good average or in need of improvement?

defenitely too much! personally, I didn't use or check esp32 but I will try to check... anyway I also use hw serial at 9600 (with esp8266) and I don't have any errors. 8 days without error...

try to check the connections, cable quality, power supply...

Power on 3,3V-PIN is ok (supply Modbus-Module too) Powered from USB-Charger (4,87V under load)

I use standard parameters: SDM sdm(Serial, 9600, NOT_A_PIN, SERIAL_8N1, 16, 17);

From what source do you get "TS Write Error Codes"?

Back to Error code 4: What mean this? Timeout? From my Modbus-Module/ESP (too slow/stuck bits)? I can't see errors on webpage if the error-counter rise (no 'nan').

do not pay attention to TS... this is my sketch which loads results to thingspeak! (and this is http error list)

so... I prepared another example, this time for esp32: https://github.com/reaper7/SDM_Energy_Meter/tree/master/examples/sdm_live_page_esp32_hwserial

and at the moment I am testing for possible errors... I won't be able to do it long enough because my home automation needs live data from my orginal sketch

in the example given above, adjust the pins to your configuration at line: https://github.com/reaper7/SDM_Energy_Meter/blob/master/examples/sdm_live_page_esp32_hwserial/sdm_live_page_esp32_hwserial.ino#L43

Error code 4 is timeout: (https://github.com/reaper7/SDM_Energy_Meter/blob/master/SDM.h#L224) and means, that in the time declared by MAX_MILLIS_TO_WAIT (default 500ms) (https://github.com/reaper7/SDM_Energy_Meter/blob/master/SDM_Config_User.h#L84) esp has not received the complete data from your meter. This piece of code starts in a line: https://github.com/reaper7/SDM_Energy_Meter/blob/master/SDM.cpp#L110 esp in a loop checks the uart receive buffer until the complete 9 bytes are received or if MAX_MILLIS_TO_WAIT time is exceeded. In your case the second situation occurs...

At the beginning Eliminate the first visible problem, lack of full 5V voltage and change the power supply to a more powerful...it doesn't have to be, but it can matter.

my esp32 after half hour (~4200readings without error)
reading 5 registers every 2sec

EDIT: after 2:15h

EDIT2: after 3:13h and 26815 readings ;)
