Anyone at all? Espressif are currently away on CNY holidays.

Hi all

I'm using ESP32-S3-MINI-1U-N4R2 modules with external 1/4 wave whip antenna with a short 30mm W.FL to RP-SMA adapter lead. I'm having some interesting issues with range I'm wondering if someone hear has had similar and knows any solution.

I have one ESP32 running in AP mode. I then have 2 ...

No EMI from motors or anything special when it's in moving around. I have tried with the antenna in all orientations. It happens if you hold your arm out and wave it around - always direct line of sight to the access point. Also happens if you just walk around lazily, again always keeping it direct ...

Current ESP32 chips don't have integrated propulsion systems so I wonder what makes your chip "move around".
Some kind of electric motor by any chance?

Yeah I've attached a 1HP motor (human power) to it. . The human has legs and arms.

Hi all

I have an application where my ESP32 is receiving a fairly constant stream of UDP packets whilst it is physically moving around. I find that when I get about 20 meters (60 feet) away from the access point, that there starts to be a lot of packets dropped (maybe like 10-20%) if moving around ...

It also seems that the ADF only has encoding functions and nothing to decode the Opus?

Hi all

Looking for any examples of streaming audio using OPUS codec. The codec examples in the ADF are for reading from a SD card and using the AAC codec and there's little documentation around it anyway. I'm trying to read from a TLV320 audio codec chip (got this working ok), compress the audio ...

Thanks for the help. I suspect it's all too hard for my little brain.

Hi Ehab

Did you have much latency? I've always wanted to have a mesh intercom system around the house/yard/shed etc, including portable units I can carry around. - Matt

I didn't get very far, but its not my area of speciality either. I was only trying to send voice which is very low bandwidth.
