Re: phy_init: failed to load RF calibration data
PIN VDD is 3.28V,10uf+0.1uf cap on the power input.
The module burned fileexamples/get-started/hello_world, it worked normally.

Re: phy_init: failed to load RF calibration data
this module is on a PCB design .And the PIN VDD is 3.28v,10uf+0.1uf capacitors on the power input.
When I use this module on a PCB design burned esp-idf/examples/get-started/hello_world,it can be uesd normally NOT restart.

phy_init: failed to load RF calibration data
hello I'm having a problem with using the WIFI from the ESP-WROOM32. file: smart_config burning with make flash ESP32-DevKitC can be used normally. But when the ESP32 module is used, it is constantly restarted. phy_init: failed to load RF calibration data rst:0xc (SW_CPU_RESET),boot:0x13 (SPI_FAST_F...
