No "Ready" Prompt after loading ESP32_AT_V1.1.3
I have been able to load the AT firmware ESP32_AT_V1.1.3 but when it boots, It stops in the middle (I think) and I never get the ready prompt. Here is the log: ets Jun 8 2016 00:22:57 rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0...

ESP32 WiFi to Serial Bridge
Is anyone aware of the availability for the ESP32, specifically the ESP-WROOM-32 module, a port of the JeeLabs ESP-LINK firmware? Is anyone working on an equivalent for the ESP32? Is there any other firmware available that provides a WiFi to Serial bridge using TXD0 and RXD0? Thanks in advance for y...

Re: Prototype circuit design ESP-WROOM-32
No, the adapter I am using is 3.3 v to the ESP-WROOM-32. The problem was that the signals were inverted out of the FTDI adapter, so I inverted them in the FT-232R EEPROM setup, it works fine now.

Re: Prototype circuit design ESP-WROOM-32
I figured out that the circuit did not have the required TX and RX inverter gate, that is why the data looked garbled. I researched it a bit and found that the FTDI FT232R chip I was using has a way to invert the signals on TX and RX so I did that and now the data look great. I hope this helps other...

Re: Prototype circuit design ESP-WROOM-32
I have attached the UTF-8 encoded serial stream that I get out of the module when booting. Perhaps that will give a clue as to what is going on.

Re: Prototype circuit design ESP-WROOM-32
I am curious if anyone sees anything obvious with my circuit design or has an opinion about what would cause an issue resulting in the garbled traffic on the port.
Thanks
Thanks

Prototype circuit design ESP-WROOM-32
I am integrating the ESP-WROOM-32 into an existing controller design (commercial) that previously used the RN-131 WiFly module. I have attached the schematic for the ESP-WROOM-32. I have connected a USB to Serial adapter (FTDI) that has been verified and is working fine. I power up the prototype boa...
