  @ipodlux Found it! in order to compensate the slow reading of the interrupt I moved the reading in the loop. It less less classy that the external function but now it reacts as it should.

  @mittech Curious as to how it went (has gone) with your Mesh application? Any consideration of ESP-MDF? What tool chain/development environment are you using?

  @conrad i use uPyCraft to transfer files to atom. You can also connect uPycraft with atom and use REPL (something like command shell) to use interactive micropython command interpreter). With UiFlow it is possible but you must first transfer libraries to /apps folder in flash memory and use advanced->execute->execute code to run appropriate commands, ewentually write raw code in Python </> tab. In this option code probably properly run only when you download it to device (not run with play button). If i find some free time then i create custom block to scroll text using recently added Hardwares->Rgb->set atom matrixblock, but i must do some experiments with it.

  @f3rn4nd0d I got "no module named 'wifisetup'" error, and without that, no 'strftime' in time... What am I missing in Mycropython for my M5Stack Gray? Thanks for your help.

  you can try this pice of code which is working for me: . . #include <WiFi.h> #include "Free_Fonts.h" #include <M5Stack.h> const char* ssid = "your_host"; const char* password = "your_password"; WiFiClient client; void setup() { M5.begin(); // Connecting to WiFi: M5.Lcd.setFreeFont(FM9); M5.Lcd.setTextSize(1); M5.Lcd.setTextColor(TFT_WHITE); M5.Lcd.print("\n\nConnecting to "); M5.Lcd.println(ssid); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { M5.Lcd.setTextWrap(true); M5.Lcd.print("."); delay(500); } M5.Lcd.println("\nWiFi connected"); delay(1000); M5.Lcd.fillScreen(TFT_BLACK); } void loop() { showWifiStrength(); delay(2000); } // show Wifi-RSSI level (signal strength in 4 bars + dBm ) void showWifiStrength() { int WifiRSSI = WiFi.RSSI(); M5.Lcd.fillRect(40, 0, 68, 15, TFT_BLACK); M5.Lcd.setCursor(40, 14); M5.Lcd.print(String(WifiRSSI) + "dBm"); if (WifiRSSI > -50 & ! WifiRSSI == 0 ) M5.Lcd.fillRoundRect(26, 1, 5, 12, 1, TFT_WHITE); else M5.Lcd.fillRoundRect(26, 1, 5, 12, 1, TFT_DARKGREY); if (WifiRSSI > -70 & ! WifiRSSI == 0) M5.Lcd.fillRoundRect(18, 3, 5, 10, 1, TFT_WHITE); else M5.Lcd.fillRoundRect(18, 3, 5, 10, 1, TFT_DARKGREY); if (WifiRSSI > -80 & ! WifiRSSI == 0) M5.Lcd.fillRoundRect(10, 5, 5, 8, 1, TFT_WHITE); else M5.Lcd.fillRoundRect(10, 5, 5, 8, 1, TFT_DARKGREY); if (WifiRSSI > -90 & ! WifiRSSI == 0) M5.Lcd.fillRoundRect(2, 7, 5, 6, 1, TFT_WHITE); else M5.Lcd.fillRoundRect(2, 7, 5, 6, 1, TFT_RED); }

  N

  To start understanding the functioning of the sim800l module I used the following example: //Reset resistance is not soldered. If necessary, weld it yourself. #include <M5Stack.h> #define RX_PIN 16 #define TX_PIN 17 #define RESET_PIN 5 void header(const char *string, uint16_t color){ M5.Lcd.fillScreen(color); M5.Lcd.setTextSize(1); M5.Lcd.setTextColor(TFT_MAGENTA, TFT_BLUE); M5.Lcd.fillRect(0, 0, 320, 30, TFT_BLUE); M5.Lcd.setTextDatum(TC_DATUM); M5.Lcd.drawString(string, 160, 3, 4); } void setup() { M5.begin(); header("SIM800L AT command", TFT_BLACK); M5.Lcd.setTextFont(2); M5.Lcd.setTextColor(TFT_WHITE, TFT_BLACK); M5.Lcd.drawString("Please use serial port to Test AT command.",0, 35, 2); // Host serial communication Serial.begin(115200); // SIM800L serial communication Serial2.begin(115200, SERIAL_8N1, RX_PIN, TX_PIN); pinMode(RESET_PIN, OUTPUT); } void loop() { //AT instruction write if(Serial.available()){ Serial2.write(Serial.read()); } //AT instruction result if(Serial2.available()){ Serial.write(Serial2.read()); } delay(10); } I sent some at command to understand if the module worked but apparently it doesn't work. Any suggestions?

Thank you very much this is a super great manual with UI-Flow and Python examples. greeting skink Thank you for reading it, Other languages are planned, I'm just sorry that it is taking me so long to write it.
