Hello

could you suggest us the best rework to support SD mode in four bits mode for the M5 stack, hardware and firmware, Library available in Arduio, ....
The purpose is to get the same base for all of us..

Schematics with suggested reworks ?
And code Library when available...

Waiting for this improvement when available and new versions..
Thanks

Hello

any update of demonstration source code for the sim module with realtime streaming audio over Gsm ?

Looking for using it as a basic talking only smartphone in full duplex, send and receive at the same time ?
If possible Under Arduino IDE , with ino file ...
Good project and information..
...
Great day.

Great thanks..You are right : add the zip Library fails, and cause my problems.
As you suggest with Include ..
It compiles now ok.
THANKS

Great project and work ..
Can we record realtime data on SD card without streaming over Wireless at the same time...
What is the maximum rate to record on local SD as oscilloscope with one-two signal ?

Great multi-application ...
Can it be a sd-card image to update too ?

Good stuff and waiting for both Bluetooth and wifi ...

Bravo

Here is github for one example with BLE only..

Library problem.....
Any suggestions, idea, to help and recompile the good factorytest.ino example ...

Waiting for your support and have a good day...

Hello

just for information :
https://www.espressif.com/sites/default/files/documentation/btble_coexistence_demo_en.pdf
Expressif seems to get both Bluetooth on going...

How to combine-create a new blufi.ino code with both wifi and dual Bluetooth at the same time too ..
https://github.com/espressif/esp-idf/tree/master/examples/bluetooth/blufi
...

Ok if a new lesson is possible...
My be subject : low power, high speed logger on sd card in bit mode (?), and then transfert over Bluetooth or wifi ..
Best Regards.

Hello

where and what is the best firmware version number including WIFI and dual mode of bluetooth at the SAME time ?
Any weblink and source under Arduino too is welcome.

At the same time, wondering for low power, and uSD card speed/read/write ( 4 bit SDIO mode ?) to store information very quickly for high speed from few SPI devices (or I2C)...

Keep going on the nice and good M5 stack device...
Best Regards
