Gsm (Sim800) blynk connection issue

I tried to use sim800 example on blynk and I am getting this issue. it seems it’s failing when trying to connect is log. I also tried 8080 port. result is same. also I tried on local server and result same. can anyone had same issue ?

Well, for me it works very good. Can you check with another SIM? Preferably different operator.

which version of library and server ? I can connect my server with http client but I can’t connect my server from blynk. I don’t think due to operator but I will test when I found another operator sim.

Library 0.5.1,
TinyGSM 0.3.2,
Server 0.38.2 (and earlier)

ok i will try with your library version and let you know.

ok it seems problem about baud rate. 9600 isn’t enough for reliable commands. I changed sim module baud to 115200 and it seems problem solved

edit: if module power down but mcc still power up, blynk can’t handle connection again. is it just for me or did you tried that @marvin7 ?

Perhaps… Personally never tried baudrate that low.

Sorry,but I don’t get this scenario… If module is down, then what kind of connection handling you have in mind?

for example main mcu is esp8266 and gsm is sim800. mcu can’t connect again if gsm connection down.

If GSM/GPRS connection fails, it reconnects. On reboot of MCU I do have a power cycle of GSM modem programmed. But this all needs to be handled by code. Without handling reconnect only occurs when disconnected from server (in case of DDNS, for example)
