Using BLE 4.2 and DLE

Does the ESP32 support the DLE (Data Length Extension)? This is different than the MTU, in that DLE actually allows BLE packets up to 251 bytes, whereas (in my understanding) MTU just allows multiple packets to be combined to a larger payload size.

Re: Send data from one ESP32 to another

We are successfully using WiFi and BLE on the same ESP32 device. But we did have to increase the flash partition size to 1.3 Meg.

Re: ESP32 Support BT5?

Yes! We also would be very interested in using BT5, and would love to know if/when it may be included on the ESP32 platform.

Re: Newbie question

For what it's worth, I've found DiffPlug to be a nice (free) diff tool under MacOS. And I used WinDiff back in the days when I labored under Windows... :-)

Re: Forum search fails often

I also find that searching within the forum often fails (or just never finishes), and that Google searching is more likely to yield useful results.

It would be great, however, if the forum search feature could be fixed (improved).

Re: Raw RF data

We are using ESP-NOW, but only sending broadcast packets. We are not defining any "peers", and so have a connectionless environment. (We implemented a source address in our proprietary packet data implementation so we could address individual devices, while maintaining a connectionless environment) ...

Re: Will ESP32-WROOM-32U be damaged if operated without an antenna?

Thank you, ESP_Angus. We have had similar results - meaning we have run without an antenna at various times without noticeable damage. But recently we noticed one unit that had unexpected (highly variable) RSSI readings - even with an antenna attached. Our theory is that the unit was operated withou...

Will ESP32-WROOM-32U be damaged if operated without an antenna?

Is it possible to damage the 2.4 Ghz transmitter if I transmit WiFi or BLE packets on a WROOM-32U without an antenna connected?

Re: ESPNOW Slower than expected RTT (Round Trip Time)

Awesome!

I am interested in the result of your further testing. We are also excited to have the higher performance, but am concerned that it may reduce reliability...

Re: ESPNOW Slower than expected RTT (Round Trip Time)

Unfortunately, the documentation is quite limited. And we have only tested this in the lab - we have not commited to changing the bit rate in production yet. Here is what I know: In `esp_wifi_internal.h` there is: /** * @brief enable or disable transmitting WiFi MAC frame with fixed rate * * @attent...
