Re: stack overflow while using multiple UARTs

If you develop with windows I prefer Teraterm over the monitor. It won't crash on a binary char. You can write it to a log file and use HexEdit to see exactly what those problematic non-ascii values are. You should ensure that you terminate the end of your recv'd data with a zero before calling prin...

Re: stack overflow while using multiple UARTs

I checked stack usage of one of my tasks both before and after printing to the terminal. Performing a print increased the stack requirement by almost 1K. This was done by dynamically changing the flag to print while running. So the task had been running long enough to not have any other things going...

Release 3.1.4 or 3.2?

I see there are official releases for both 3.1.4 and 3.2. I am currently on 3.1.3. I chose to stay with official releases and I believe the 3.1.x were the only official releases. Now we have both 3.1.4 and 3.2, and I am unsure of the criteria to make a choice. Why are there two branches of official ...

Re: ESP32 roam behaviour

I'm just wondering if there are any news regarding WiFi roaming? Is this still down to programmatically scanning SSIDs and deciding upon the RSSI value if I want to switch to another AP? I doubt there is more news. You can assign a specific AP by using the BSSID. We did that by letting the phone ap...

Re: Wifi dropping and having issues.

I believe I know what the problem is, and it doesn't have anything to do with NVS. At the same time as creating the 2nd NVS I was using a new daughterboard that didn't have a pin clipped on the connector. It was putting 5V on GPIO 00. Not sure if that could cause the problem but I'll know when I cli...

Re: Read registers using C code?

READ_REG works for me for reading EFUSE_BLK3_RDATA6_REG. I'm using it in a CPP file, but doubt that would make it compile better than C. Since you didn't bother to list the compile error, you won't get much help here. But I'm guessing it's a missing header include. Or maybe those registers require y...

Wifi dropping and having issues.

Not sure if this is a coincidence and I've only tested with one device so far. When I switched from having one NVS partition to two the wifi on my device started having issues with connecting and dropping on a frequent basis. This isn't a wifi issue overall because all the ones running with the sing...

Re: ESP-WROOM-32 Problems programming with esptool.py etc

I get the same problem sometimes when using a USB extension cable. Then I have to use the BOOT/EN buttons to initiate download mode.
