My application with the BC127 will be within a meter from the host smartphone. I’ve combed through the datasheet and I cannot find any mention of turning down the RF output power. The spec page for it on Sierra’s website mentions that its <10dBm for BLE and <4dBm for BT Classic. Is there any way to tune this down to say 0dBm or -2dBm for both?
I would like to save as much power as possible, and preferably change the power dynamically on the fly (e.g. ramp down RF power during idle states or unpaired and ramp it back up during music streaming). But I assume the only way I can adjust it period is to mess with the PSKeys?
Alternatively, I’m figuring out how to configure the timeout from when the chip receives a UART character during deep sleep and when it goes back into deep sleep? The datasheet mentions a 1 second delay, but I keep running into the ERROR 0x0012 problem, even when I include an extra CR before and some delay. As well as the timeout of going into Deep Sleep while connected.
