* rx signal measurements -3 marginal, -9 bad, 10 great, -10 means almost unusable. So scale this into % signal strength. preferably as a graph, with an X indicating loss of comms.

During the beta timeframe the following improvements 'would be nice' (and yeah - I guess some of these items count as features, but it is a hobby project ;-) )
|

|
||||
* Figure out why the RF95 ISR is never seeing RH_RF95_VALID_HEADER, so it is not protecting our rx packets from getting stomped on by sends
|
||||
* use BLEDevice::setPower to lower our BLE transmit power - extra range doesn't help us, it costs amps and it increases snoopability
|
||||
* make an install script to let novices install software on their boards
|
||||
* fix the frequency error reading in the RF95 RX code (can't do floating point math in an ISR ;-)

* Use CAD mode of the RF95 to automatically find low noise channels

* read the PMU battery fault indicators and blink/led/warn user on screen

* make a no bluetooth configured yet screen - include this screen in the loop if the user hasn't yet paired

* the AXP debug output says it is trying to charge at 700mA, but the max I've seen is 180mA, so AXP registers probably need to be set to tell them the circuit can only provide 300mAish max. So that the low charge rate kicks in faster and we don't wear out batteries.
