Hello,
i am facing on a new problem :
previously ,
just after the message “Connectingto ON_AIR2021” …. (my SSID)
i was geting somme data on my YAT terminal ,like this :
…….etc …
I2C device found at address 0x20 MCP23017 2×8 Bits I/O
I2C device found at address 0x3C OLED SSD1306
I2C device found at address 0x77 BMP 085 Pression
Trouve 3 devices sur le Bus I2C
.. Fin de test I2C bus
BMP085 OK
Connecting to ON_AIR2021
…..
WiFi connected.
IP address:
192.168.0.103
MAC address:
08:3A:F2:8D:C9:94
i= 1 Press. 991 mBar
i= 2 Press. 991 mBar
i= 3 Press. 991 mBar
…. etc …..
i don’t understand ,why ,now, the Serial.print doesn’t work anymore ..
Nota :
data on web page are refreshed … OK
my Red led on D5 pin blink every 2 seconds ..OK
i cant see the IP adress on my OLED LCD.. OK
it means this part of programm is executed..but no more serial printout at all ?
i expected to get and print :
index value, DHT11 Temper & Humidity values, BMP085 pressure value , and OWS DS18B20 temp.value
project in the zip file https://1drv.ms/u/s!AobzXXeAgQ2De7C4lQhSBtfIMss?e=mFYCRR
Hardcopy of Web page and Terminal YAT https://1drv.ms/u/s!AobzXXeAgQ2Delwr4-HFUOwPAY0?e=37HH99
remark: i must disconnect D2 ( DHT1 signal) to be able to Upload my programm
else upload abort with COM port problem ..

… other details ..
i can see my values , via serial.print commandes ,
after Wifi connection ( web page is active, and Gauges values are refreshed)
via Arduino Monitor ( virtual port COM56)
if i close Arduino Monitor after the message Wifi connection
and reopen it after , so i can get the print out…
results :

This is possible only with Arduino Monitor (virtual COM 56)
if i want to use my PC Terminal YAT (same virtual port COM56 (with arduino monitor closed !)
. i just get the messsages before Wifi connecting.
no serial .print at all. after Wifi connection.
What is SPECIAL with Arduino monitor ? compare to a classic PC terminal like YAT .. wich is more confortable !

Hi.
I’m sorry for taking so long to get back to you. I was out of the office with very little access to the internet.
I’m not sure what might be causing the issue. I have used the PuTTY Serial Monitor and it worked as expected. I’m not familiar with the Terminal YAT. But, still, it should have worked.
Take a look at some similar discussions on Arduino IDE and check if there is something that might help. For example:
Let me know if you were able to solve the issue.
Regards,
Sara

hello, i followed your link, but it not a similar case .. so , i tried another PC terminal : Teraterm and i can get all messages send trough UART , from start ( connecting USB cable on EPS32 module) and also after the Wifi init .. web page showing 4 gauges .. and all values send inside the Loop .. so probleme solved by using Teraterm instead of YAT terminal .. i don’t know why ? but no need to dispense energie about that.. Thank’s for your answer. captures d’ecran
