Problem with BlynkGSM_Manager and TTGO TCALL

H_Andy_H · June 9, 2021, 11:13pm

hello,
I have a sketch, that works on a TTGO TCALL esp 32 and connected to the blynk server with wifi. No Problems. All fine.
Now I want to use the TTGO_TCALL_GSM example and I want to connected the blynk server with gprs.
I´ve loaded sketch to my esp32 and connected the esp over the 192.168.4.1 to enter my network ssid and password, the gprs apn, user and password and enter the projekt auth token. Push save and restart the esp, like the discription here: GitHub - khoih-prog/BlynkGSM_Manager: Simple GSM shield Manager for Blynk and ESP32 / ESP8266 boards, with or without SSL, configuration data saved in SPIFFS / EEPROM. This library enables user to include both Blynk GSM/GPRS and WiFi libraries in one sketch, run both WiFi and GSM/GPRS simultaneously, or select one to use at runtime after reboot.

But the esp din´t connect to my network and / or I can´t connect with the blynk app. Not over wifi and not with gsm.
This is the monitoring that I get:

I’ve tested with the same TTGO_T7_V14_Mini32 and be sure the library is working OK.
You have to read the doc carefully and correctly follow the instructions there.
I’m afraid it’s very difficult for anybody to know what you’re doing wrong and help you.

hello khoih,
thanks for your response.
I´ve nothing changed on the example sketch, except to enter the ssid and password of my network for testing and yes, I thing the library is working, but the question is what is my error.
You can see that I have absolutely different monitoring as yours. Is the somewhere a diffrent instruction, for dummys? Because I can´t find my error…

khoih · June 10, 2021, 1:57pm

Just follows the steps in So How It works.

If you still can’t make it working, you have to post in details the steps you did, along with the terminal outputs and/or screen shots (certainly after modifying the secrets : password, token, etc.). In this way, we at least can have some basic info to help you.

H_Andy_H · June 10, 2021, 10:24pm

ok, I think I find the error. I don´t have cleard the blank fields and have not entered anything new.
Now it works.

But how can I call now the configuration mode to change something? The default ip address no longer works and with the new IP of my network I can´t call the configuration mode. Do I have to turn the wifi off or is there another possibility here?

khoih · June 10, 2021, 11:57pm

Check the Features

Multi or Double DetectDetector feature to force Config Portal when multi or double reset is detected within predetermined time, default 10s.

I suggest you at least read /scan thru the README, whenever you have any issue. Don’t expect somebody to have time to help you in every simple step. I’m out now.

Good Luck,

H_Andy_H · June 24, 2021, 1:26am

It´s me again
Now I have a not so easy problem for me. I can´t find my error an need help, please.

When I connect the ttgo with wifi and gsm, I have a connection to my wifi and my gsm apn, but my sketch won´t work.

When I connect the ttgo only with gsm, my sketch will work fine, but no connection to my apn.

[Unformatted serial output removed by moderator]

When I connect to wifi with gsm manager my sketch wont work.

When I connect the ttgo with my wifi directly with the simple blynk wifi example, my sketch works fine and I have a connection to blynk.

The library has finished its job to help you connect to Blynk Cloud using WiFi and GSM. It has no more reach

What you need to be done in your sketch has nothing to do with the library. You have to fix the code yourself.

You can ask for help by opening another topic, using simplified MRE, hopefully sombody will understand and have time to help you.

Good Luck,

@H_Andy_H when you post code or serial output to the forum it needs top be formatted with triple backticks (NOT Blockquotes) so that it displays correctly.

You’ve done it correctly in your earlier posts, please do it correctly in future.

Pete.
