- HT7333 chips can only output 250mA. You need at least 500mA to be able to provide peak power for the RF bits in the chips. - The dropout voltage of this chip can easily reach >1V (@250mA) which means the ESP32 and the flash chip will only get 2.7V. While the ESP32 likely is OK with it, this brown...

Thanks. In that case I guess I will take it up in the PlatformIO forums.

Thanks for the reply. I am using PlatformIO which has its own build system, but yes I am sure it is using the correct partitions.cav file. To check this, I added both BLE and Wifi to my applications which took the size of my app to about 1.8M. This failed to flash due to lack of space. But updating ...

I have been experimenting with various partition tables on my 4MB ESP32-WROOM-32 device, and had some confusion. I am using PlatformIO for development. My original partition table looked like this: [Codebox] # Name, Type, SubType, Offset, Size, Flags nvs, data, nvs, 0x9000, 0x5000, otadata, data, ot...

I understand that, but then why does the 'esp_adc_cal_raw_to_voltage' function return a voltage when the adc is reading 0?

I have been reading and learning how to calibrate my ESP32 ADC for the last few days now. I finally seem to have done it using the following steps, but I still have a problem. 1. Route VREF to GPIO using function: adc2_vref_to_gpio 2. Measure this voltage using my multimeter (it was not too off, mea...
