BLE Connection stops adverticement on AT-Firmware
Hi. I'm thinking about using an ESP32 module with the AT commands firmware as an ALT beacon that is set up by another "Master" CPU. I've got it working but as soon as I connect with a phone the advertisement stops until I send AT+BLEADVSTART to the ESP32. I could send AT+BLEADVSTART every second or ...

Re: AWS IoT and HTTPS are mutually failed
I finally found the final answer. It was caused by the stack overflow. Which stack? I don't know. But when I reduced the size of each my stacks, it worked. I used stack high water mark to check some stacks, including the system stacks, I could reach out but found none. Anyway, it works now. Samson ...

Re: BUG: ESP32 dev board and reading sd card's (high power consumption + ESP32 hangs)
Could it be that the esp8266 powers up the SD card on init while the ESP32 powers it up on first access? The 18mA extra draw after using the SD card is probably from it being powered. If you want to stop that I would assume that you need to power down the SD card and then do a re-init the next time ...

Re: Wifi / Bluetooth Problems with custom Board
Just guessing but can it be a power supply issue?
Takes a lot more power to connect to an AP than to just scan for them.
Are you sure you can supply enough power to the ESP? Do you have sufficient decoupling next to the power pins?
Good luck

Re: ESP_LOGD crashes when a %s parameter is NULL
The following code snipplet results in a program crash: char *string = NULL; ESP_LOGD( TAG, "*** crash here %s", string ); Since the ESP_LOG * functions are often used for debugging, it is more than annoying when these functions themselves crash, because the parameters are not well defined. I would...

Re: Happy Holidays! (W/ binary for your ESP32!)
Hi Tried it with an LOLIN32 v.1.0.0 board but I got no signal on the outputs (Checked with oscilloscope). Here's the output from the flashing: c:\Users\Jimmy\OneDrive\holidays2017>python c:\esp-idf\components\esptool_py\esptool\esptool.py --port com7 --baud 230400 write_flash 0 holidays2017.bin espt...

Re: ELLO 3M 'TROLL' computer
An alternative to Python you might want to check out is Mongoose-OS. https://mongoose-os.com Then you could write your code in, a somewhat reduced, Javascript (or c++) . Mongoose-os also has a lot of cool functionality like extendable RPC support, built in webserver, FOTA and tools to easily connect...

Re: HWCrypto VS MbedTLS
Could it be that there is some over head associated with setting up the hw crypto unit that causes these poor numbers. What happens if you use bigger input and output blocks? For example En/De-crypt 256 bytes instead of 16.
