i replace radio_ to rig_ fix ok

models of ESP32 development boards compatible with the project

What esp32 board models were successfully used in the project? what boards are not recommended for use in the project?

[Feature Request]Preamble length in config

First of all thank you for your project!
I'm experimenting with LoraDV and it would be nice to have in config.h file the option to change preamble length. This could be useful in unstable and noisy propagation conditions.

Feature request - Devices locator without GPS

Thank you for your great project.

It will be nice addition to project to include devices locator with three or more devices at an edge of geographical area of interest. This will eliminate use of GPS for all devices. Example project is at link below:

Thanks.

Is it possible to add Opus for better quality audio?

I know it will reduce range with higher data rate Opus require but audio quality would be improved.

I am asking as you implemented Opus codec in your android app version. Can it be done for standalone implementation?

Thanks.

question about specific use case - one way mic/audio transmission

HI, i played around with the lora/codec2 projects and really enjoy to learn from it ! I ask myself it's possible to use 868/915 Mhz lora like the sx1276 and ESP32 to realize a one way audio transmission . I look for a way to transmit on board audio from FPV drones that use a digital video transmission at 5.8Ghz and a 868 lora based control link - I don't look for perfect representation of the onboard audio situation but for a "low latency" representation of the prop noise - rpm and the pitch level of the noise onboard would already be helpful.
In general I want to use one firmware for the sending hardware and one for the receiving side - like ESP-c3 + I2c mic on one side and one with a headphone amp on the other side.

Would codec2 and 868 Mhz "one-way lora" be able to transmit the noise from a drone or is this type of sound chaos not working for that codec ?

Any idea how latency will behave with decreasing "link quality" in a constant one-way setup ?

THX !!

i make a sch for loradv ,and i tested for heltec-v2.1

i make a sch for loradv ,and i tested for heltec-v2.1 board ,the default config tx mic ,rx spk sound is not big engouht,the sound quality is not good,but we can try more.

i nottice meshtastic module have codec2 sound tx rx function now.
it just use 4 gpio to work
I2S Word Select
The GPIO to use for the WS signal in the I2S interface.
I2S Data IN
The GPIO to use for the SD signal in the I2S interface.
I2S Data OUT
The GPIO to use for the DIN signal in the I2S interface.
I2S Clock
The GPIO to use for the SCK signal in the I2S interface.

add Reliable Packets for voice packet

hi,friend,
i 'm testing digital voice,and digital photo for lora
i 'm try to add Reliable-Packets for loradv,then we can sent digital packet in Reliable mode,this can increat distance
and voice quality.
