I am not able to use the SD card while having the CC1101 connected and viceversa.

#249 shows that the issue has been persisting for a long time, is there any possibility of a fix?

[bmorcelli]

It is not "fixable" it is just not possible without modding and adding transistors and changing the code..

When using CC1101, take the SD card out and in again after each signal saving

[AlexC-0806]

Okok understood, but why for example in CatHack firmware SD card and CC1101 can work simultaneously? I understand that CatHack is not open-source so it's not possible to verify how it works precisely, but still it could be possible to use the same approach

[bmorcelli]

It can't, actually.. if you pay attention, after you save one signal it asks you to turn off and on again to physically unmount the SD SPI inner driver, than you can save again..

And if have made use of the SDCard, you need to do this procedure again..

We could have done it in bruce, but we would lose boot image, boot sound, save configs on SD Card, etc..

So as I said earlier.. to use SDCard, you must take the card out and put again, open RF, read/save the signal, take the card out, open Menu, put SD in, open RF, read/save again
