Re: Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on CPU0)

Sorry, but I don't think it is possible. We have at least 30 tasks in a complex system running on proprietary HW - and the failure only happens rarely. I can tell you that we do not use WiFi or BT Classic in normal running mode, just BLE. We use the BLE to scan for beacons and the error occurs even ...

Re: Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on CPU0)

This precise crash occurs on our product too - it is the only reason it crashes, even when the system is left for days at a time. Since we require at least 12 hours of continuous operation it is a problem we would like to see fixed. I should also point out that it has been happening for a considerab...

Re: ESP32 with GSM modem - PPP over Serial (PPPoS) client example

I have used this example as a basis for my code but I cannot work out how the code requests a UART buffer size of twice the data buffer size (which is set to 1024). The uart_driver_install() function disallows anything above 128 bytes for Tx or Rx, the size of the hardware UART FIFOs. If someone cou...

Re: BLE power consumption

We are looking at using ESP32 for several products. BLE will be a critical factor in the design. We have measured the current used and see that having only BLE operating, listening to advertising only uses basically the same amount of power as WiFi does. This includes the case where no WiFi is opera...
