Still no WiFi AP on startup. This time I tried to activate with a pybytes activation code
and reflashed the firmware. I also tried sending this command over the serial port via pymakr
.
pybytes.activate("activationkey...")
Disconnecting current connection!

Please review Wifi SSID and password!
Activation failed!

Any hints?
Version via REPL: (sysname='LoPy4', nodename='LoPy4', release='1.20.1.r2', version='v1.11-06dfad0 on 2019-11-30', machine='LoPy4 with ESP32', lorawan='1.0.2', sigfox='1.0.1', pybytes='1.3.0')
Inspite of the blue heartbeat, there is no WiFi AP after starting the lopy4 device.
esptool.py erase_flash
and later successfully updated the firmware to1.16.1
using thepycom firmware update tool
on Ubuntu 18.04./dev/ttyUSB0 (Slilicon Labs)
to erase flash and update firmware on the lopy4.miniterm.py
, I can see the python terminal and can execute basic commands like changing led colors.Below is the print I see on bootup
This leaves no option but to type out each python command on the terminal, rather than using easier ways of ftp https://docs.pycom.io/gettingstarted/programming/ftp/ for uploading code to the lopy4. Also, to be clear: I do not posses any expansion board/Pytrack/Pysense/Pyscan device and have been using a usb-serial-uart module for formatting, upgrading firmware or uploading code.
I read on https://forum.pycom.io/topic/5338/no-lopy-4-wifi-after-updating-the-firmware about similar problems of not having WiFi AP on update, but wanted to verify if it was solved. My final objective would be to try out the
pymesh LoRa
on two/three modules of lopy4.
