Re: Opus codec on ESP8266

Hiu isti37. Is this for a commercial project or is there a chance you would consider sharing the code/project? Kind regards Jimmy Fixed, I managed to compile the opus codec with the esp-open-sdk and the virtualbox environment : sudo ./configure --target=xtensa-lx106-elf --host=xtensa-lx106-elf &...

Re: ADC strange issue

Hi again Lee What you could to to solve your problem with the high impedance voltage divider resistors is to use a ]voltage follower (See: https://en.wikipedia.org/wiki/Operational_amplifier_applications#Voltage_follower_.28unity_buffer_amplifier.29 ) . It's just one simple OP-amp, could be as small...

Re: ADC strange issue

Hi Lee My guess would be that your sensors resistance is to high and can't supply the ADC with the current needed during sampling to fully charge the sampling capacitor. Resistors of at least a factor 10 lower resistance should help. Other things that help is lowering the sample speed if possible as...

Here's more regarding skipping the first entry (Nothing about them(espressif) removing it though): http://bbs.espressif.com/viewtopic.php?f=66&t=697 Regarding bssid) vs ssid that's probably because what it listed is actually ssids and not bss(id). BSSID is the (unique)MAC of the AP found, multip...

Re: Unreliable setup

The voltage regulator on your uart<->serial converter can't supply enough power for the peak usage of the Wifi module. Attaching a large cap. to the 3.3v most likely won't be enough. So power the module from separate power supply with 3 - 3.3v output. Disconnect the power from the USB module and mak...

Re: Very high packet loss UDP with Apple Iphone 4

Hi Just some thoughts. When developing an IOT device with IOS controller app we also found that there was problems with high UDP packet loss. And this wasn't with an ESP8266 but a CC3000, so I would guess that the problem is in IOS, as is also suggested by the fact that the PC got all the packets. I...

WIFI doesn't connect to strongest AP

My experience is that, when there are multiple APs with same SSID( & passsword), the chip doesn't connect to the one with the strongest signal but instead the one with lowest channel ID. Seems like it scans from low to high channels and connects to the first AP it finds with the right SSID. Seem...
