Re: How to turn on/off the BLE and WiFI radios
I am also looking for this. I have tried various combinations of bluedroid_enable, bluedroid_disable, bt_controller_enable, and bt_controller_disable but once it is disabled I can't figure out how to reenable functionality. I have also tried to initialize everything using the init functions and then...

ESP-IDF Eclipse Plugin C++ Unresolved Includes
I followed exactly the guide to install the new Eclipse plugin for idf projects found [here][https://github.com/espressif/idf-eclipse-plugin] and I got it to build successfully. I also got it to build successfully when the main file was .cpp as opposed to .c. However, in both cases I ran into unreso...

ESP32-WROVER-B "flash read err, 1000" on hard reset, otherwise is completely functional
I have a pcb that previously accomodated a ESP32-WROOM with 4MB flash. I switched it to work with a WROVER, and the module I am currently using is a WROVER-B with 8MB PSRAM and 16MB Flash. The pcb was completely functional with the WROOM module. I changed menuconfig to 16MB flash and enabled externa...

Re: WiFi current spikes mediation
I think I fixed the problem! I received the new design which had proper board design(the esp-wroom32 module attenna was hanging off the side of the board and NOT on top of the ground plane, see the esp32 pcb design tips for further info), and greatly increased capacitance, namely a 1000uF capacitor ...

Re: WiFi current spikes mediation
At the very least its nice to hear others are having the same problem! I also observed it in bluetooth operation, though it was more intermittent. This might be more due to the nature of bluetooth vs WiFi, though I don't know the exact architectures/implementations of either so I can't comment. I di...

WiFi current spikes mediation
I currently have an ESP32 dev board running on a PCB which includes an audio circuit read in via I2S using an external ADC. Without wifi enabled, the circuit works flawlessly, albeit with a bit of negligible power supply noise. However, as soon as the wifi is turned on, there is significant noise in...
