Hi all,
the nRF54L15 hardware can support an external RF antenna switch. I don't see any hardware limitations (the switch could be controlled via GPIO), but the more interesting question is whether the software can handle a real antenna switch (antenna diversity).
As far as I know, there is currently no ready-to-use automatic BLE antenna diversity API for normal BLE communication. It seems to be implemented only for Channel Sounding. True per-packet diversity would require radio-level support, which is not currently provided as a standard Nordic BLE feature. At least, I haven't found anything about it in the documentation.
My question: Is antenna diversity support for standard BLE planned for the nRF54L15, or is there an existing solution for it?
Best regards
Maik
