@joseph I'm afraid I can't give you a timeline. The BT mesh is developed by Espressif, once they release it, we can start working on the implementation. We'll update the forum when we have a development version ready.

I have the same problem with some of my GPY. You are powering the GPY with 5V? Cumps,

@jclo13 Two general guidelines has been ignored in the github post, which are sensor & ground isolation and duration of excitation : “ Sensors must be powered individually, and the ground must be isolated from sensor to sensor. Even if powered individually, an open ground path to another un-powered sensor can't be allowed. This is best accomplished using multiplexers to open and close the appropriate channels. “ For additional details please refer to : www.irrometer.com/200ss.html

@archana-kadam Just add micropyGPS.py to your project folder and add import micropyGPS to main.py. If you have trouble uploading the file you should read the documentation.

@tschili Imho, if you trigger the wake-up just when the transmission starts, you'll have the issue that the GPY needs to little bit of time to wake-up and initialise, and you will most certainly lose and data received during that time. So you would need the SIM800L to wait until the GPY is ready to receive before it start sending the data, and some other way to wake up the GPY.

@archana-kadam I looke dagain at you request. What I cannot understand is, why you do not simple set the respberry Pi to 115200 baud. Besides that, you can free UART0 from the REPL and reconfigure it to any speed you like, e.g. for 9600 baud: import uos from machine import UART uos.dupterm(None) uart0 = UART(0, 9600) Be aware, that after the "uos.dupterm(None)", the REPL and print etc. is on telnet only.

@kebson Thinking about your message, I assume that you connected the collector of the transistor to GND and control the relay though through the Vcc & GND pins of that relay board. Two topics are to be discussed: Current draw. According to the data sheet, the coil resistance is 70 Ohm, resulting in an current of 47 mA at 3.3V. At that load, the output voltage should be lower than 3.3 V, so it might "just" fit. At about 3V, the force at the relay contacts may be lower than at 5V, causing higher relay contact wear. Flyback voltage peaks. If you did not remove the flyback diode from the board, that might work, at least for a while. But still I would not consider to connect an inductive load directly to the ESP32 output pins. It may work for a while, but then break. B.T.W.: What is the mains voltage/power of the Pump?

@jimpower The load sensor combinator shown combines four half bridge load cells in a way, that it looks like one full bridge load cell. It is a pure passive board simplifying the wiring. The output has to be fed into a load cell amplifier and digitizer.

@jmarcelino We have already added the file mqtt.py, and main.py is blank Thank you

Per comments from @robert-hh & @timh , I used a MAX3232, RS232 to TTL converter chip to resolve the issue.

@pmb_nl Actually you should be able to run Arduino on it: https://forum.pycom.io/topic/3134/using-pycom-boards-with-arduino-ide/1

@archana-kadam Normal LTE no.. unless you use a WiFi-LTE router (MiFi) or external LTE modem.

@seb said in threading - thread starts, but main does not run: https://github.com/pycom/pycom-libraries/issues Ta. Opened; https://github.com/pycom/pycom-micropython-sigfox/issues/158

@jmpratt Would you mind providing me a link for the hardware you used? I was thinking of using the RS485 library and a 485 to uart breakout board.

Functions and methods are actually different things and exist in different scopes. You can't look up a method by name without the self. (or similiar) prefix. Unless you bind it to another name in the current scope. The same applies to class methods.

@sunrise17 you must modify esp_get_revision - i do not have guide but on the forum you can find such posted by @robert-hh https://forum.pycom.io/post/13828

@rskoniec Thank You sir
