Re: How to new a project?

@Ritesh I think the OP does have a point: the examples are just that, examples. It is conceptually incorrect to say "take an example and modify it", when the OP asks for a template, because in the example it's not really clear what is mandatory and what is part of the example. It would be much bett...

Re: ESP32 connects to Access Point but can't get IP address

Thank you WiFive and Ritesh for your precious hints... Finally I could try to debug ESP32 DHCP client behavior and discovered that there was a problem with last ARP check during DHCP sequence... This seem to be a known issue with "enterprise" access points, like Cisco Aironet Enterprise AP. Therefo...

Try enabling dhcp debugging in lwip header files. Also consider trying newer versions of esp-idf.
Yeah. That will be also helpful to find out exact issue.

Re: Question on adc1_get_raw

Hello everyone, I know adc1_get_raw is blocking cpu on polling meas1_done_sar. while (SENS.sar_meas_start1.meas1_done_sar == 0); Can we add taskYIELD() to make it slightly efficient? while (SENS.sar_meas_start1.meas1_done_sar == 0) taskYIELD(); Thanks, John What issue you are facing after adding th...

Re: ESP32 connects to Access Point but can't get IP address

Hello ESP32 forum, I'm developing an application using esp-idf_v3.1.1. ESP32 is configured in WIFI_MODE_APSTA mode, working at the same time as access point that accepts connections from WiFi clients and as station. The system usually works as expected with most access points... but... there are a ...

Re: Is flash read err, 1000 normal behavior?

I have two different products and both show the following messages when I reset them using a reset button that pulls EN low. I am sure bootloader is programmed (programming step showed success on that). My application seems to run okay, but I would like to understand if this RTC WDT is normal. ets ...

Re: WIFI/BLE Simultaneously

ESP32 needs to collect heart rate data at the same time it is sending previously collected data over wifi. Heart rate sensor sends heart rate data to ESP32 once every second. Forming wifi connection to router and sending previously collected data to database takes about 4 seconds. Would this work? ...
