Your comment is dead on - I had the resistor connecting the PCB antenna not soldered, but instead the bridge connecting the IPEX connector was on. I spent half a day looking for solution in code...
Thanks!

ESP32 DevKit C V4 - very weak WiFi signal
I am trying to use an ESP32 DevKit C V4 board with WROVER-B module, however the wifi signal is extremely weak. When in station mode, scanning returns only two access points (there are many more), and the strength of the signal from my router is -70 dBm when the board is next to the router. When I pl...

Re: Deterministic functions
Thank you for the detailed explanation - using an external flip-flop will probably do the trick, I'll give it a try.

Deterministic functions
I have a RPi Pico board which I am using to output a trigger when a certain message is sent out via the UART. The code is: uart.write(cmd) trigger_pin.on() # This is the important trigger edge response = uart.read(n) trigger_pin.off() Using a scope, I can see that the pin is not turned on at the sam...

Unable to set hostname
Hello, I'd like to set a hostname for my ESP32 board, and the code I am using is: self.wlan_sta.connect(ssid, password) self.wlan_sta.config(dhcp_hostname = self.hostname) After that if I print out the hostname, it's the same as the one I set; however my router just shows the name espressif. If I mo...

Re: uasyncio and inaccessible REPL
It's not only Thonny - rhsell and Mu can't connect either.
Tried adding the code from above, but that did not give any results.

Re: uasyncio and inaccessible REPL
Thank you for the input. That is certainly a way to rescue your files after being "locked out" of the REPL, but doing that every time you want to reprogram the Pico or make small changes to the existing firmware is too much overhead. What I've done now, to keep me going, is connected a push button t...

Re: uasyncio and inaccessible REPL
I tried Putty (Windows & Linux) and Moserial (Linux).
The script that does not terminate is loaded with Thonny and named main.py.

Re: uasyncio and inaccessible REPL
Tried that on both Windows and Linux, not working except when I initially flash the board. Once I exit Thonny, there's no way to get the REPL when starting it again, ctrl-d and ctrl-c both fail.

Re: uasyncio and inaccessible REPL
Is there a way to interrupt that script, and get the REPL? I am stuck on that.
