Re: Starting WiFi with custom mac address
Thanks ESP_igrr. I have (almost) succeeded. For anyone else wishing to do something similar, I am posting working code here. First of all, you need to include #include "soc/soc.h" #include "soc/rtc_cntl_reg.h" #include "esp_wifi.h" byte mac[6]; Then you can read the mac, change it and reset it using...

Starting WiFi with custom mac address
Hi Guys, I have a project which involves a number of ESP32's with Ethernet modules reading from sensors and sending the sensor info to a Client PC running a Python app as and when the client requests said data. So that I can identify my ESP32 modules on the network, I assign them all a mac address s...

Re: ADC speed?
I also need a higher sampling rate. Is there any way to get good results with higher sampling rate than 6Khz? External adc is no solution for me I’m afraid it would seem not. Your only option with the ESP32 is an external ADC. The STM32duino (BluePill) can sample much faster but has no WiFi or Blue...

Re: ADC speed?
I found out by experimenting that I can read the adc’s at a much higher rate than 6k but that the data is garbage. If I sample vibration readings from a motor at say 4K sps, I get a peak at the correct frequency when I do an fft but if I sample at a higher rate than 6k, the peak is not at the correc...

Re: ADC speed?
Yes, I know I could use an mcp3208 and get higher sampling rates, I designed and sold an 8 channel board for the raspberry pi on eBay and got 100ksps no problem. It’s an option of course but if there’s any way the internal ADC can get a higher sample rate, why waste money?

Re: ADC speed?
Hi, I have a vibration analysis project. I have been using the stm32f103 which can get high sampling rates with analogRead() and even higher using DMA but I want to go wireless and the ESP32 seems the logical step forward. Whilst 6 ksps is ok for most of my application, Lubrication deficiency shows ...

Help with strings
Hello, This post is a request for help using painlessMesh , but it is to do with string manipulation above all else. I am creating a character array of 65536 elements representing 32784 ADC readings. The ADC read routine is rdg=analogRead(ADC0); twf[a]=(char)encoder((int(rdg/64))); twf[a+1]=(char)en...

Re: painlessMesh (the painless way to build a mesh) now also supports ESP32
Hi Blackedder,
I have been trying painlessMesh and it seems that it might be the answer to my quest so I have a cunning plan to use it! Thank you for your hard work and for making it available.
Can you tell me what is the maximum number of nodes connected in the mesh?
Regards
Steve.

Re: Is it possible to use the code ESP8266_MESH_DEMO in ESP32?
Is this available yet? A few months have passed. Fingers crossed, Steve.ESP_Sprite wrote:We have code for ESP32 meshes in development, however it is not finished yet. We should be making something public about it in a month or two, however.

Re: Wi-Fi : Client server data transmission
Hi Rakesh Can I ask you what your project is, it sounds like we need a similar solution except I need much more data sending and I dont need to collect that data within a period of time. This is what I have done so far https://github.com/BaartCM/FFT-Analyser/blob/master/BaartFFT.zip the pc requests ...
