CC1101

Connection pinouts

NOTE: CC1101 support is still experimental and not fully tested. Also not yet available in the official releases

To use the CC1101 in Bruce, turn off your M5 device and connect the module following the pinouts listed in this page.

Turn on the device, then navigate to Config->RF Module and select "CC1101 on SPI" (pics here).

If the "CC1101 not found" error message appear, turn off the M5 device, recheck the wiring and try again.

If no error is shown, then the CC1101 is initted correctly, and you can use it in the RF menu.

For this module you can also set a custom operating frequency in the supported subranges: 300-348 MHZ, 387-464 MHZ and 779-928 MHZ. Setting an empty or invalid frequency will reset to the default 433.9.
