Both are correct.

I have used the non-antenna boards from this vendor.
He is also good to work with if you need custom boards.

I ran a quick test with a single 1.1MB file and got the following results using an 8K chunk size: Total read/send time: 4.6 secs, measured in ESP32 code. File read time (no sending): 2.24 secs Transfer testing was over wifi --> router --> gigabit network --> PC. ESP32 is about 5 ft from wireless rou...

Just a couple of suggestions: 1. For the smaller files--smaller than your 10K chunk buffer--I would just send them in one step with content-length in response header. 2. If you are sending chunks based on the example given in file_server.c (under protocol examples),there is a problem in that code in...

In Beta3 and ongoing development examples, in "protocols/.../file_server.c", a terminating chunk with chunksize = "0" is sent twice--once in the do-while loop and again in a closing line. This probably doesn't affect IExplorer, but Firefox (latest beta version) doesn't handle it well--frequently los...

I'm assuming C code. Something like the following should work: int arr[][2]={{11,12},{21,22},{31,32},{41,42},{51,52}}; int i,m,n,*j; // m=5; // n=2; // show(arr,m,n); void show (int *b,int l,int p) { int i,j; printf("show \n"); for(i=0;i<l;i++){ printf("%d %d \n",*(b+i*2+0),*(b+i*2+1)); } } void mai...

Programmable sample time on the ADC.

I'm not sure what is going on with the forum. I attempted to post a reply previously and I got logged out. About your measurement, I did a test using GPIO39 (ADC1 Channel 3) and found that 3.14vdc input resulted in 4095 counts. I decreased the voltage and saw a corresponding decrease in the AD count...

Hello, I just ran a test with ADC1_3. I used voltage ranges from 0 to 3.2vdc for input. Just for a quick test, I used the common power supply ground for the analog ground. I read 4095 counts at approx 3.14vdc. If I decrease the voltage, I see an expected drop in the counts. It appears to be function...

I'm testing the adc1 for use in an application. With the 2V scale attenuation and using a 1.6 volt battery at the input, the average readings are about 860 or so. I'm aware of some linearity problems, but the main issue is that the readings from 660 to about 990. I am using the following code snippe...
