+- write UC1701 wrapper
+- scheduleOSCallback doesn't work yet - it is way too fast (causes rapid polling of busyTx, high power draw etc...)
 - find out why we reboot while debugging - seems to be power? try using external supply
 - DONE install a hardfault handler for null ptrs (if one isn't already installed)
 - test my hackedup bootloader on the real hardware

 - make ble endpoints not require "start config", just have them start in config mode
 - measure power management and confirm battery life

+- do initial power measurements, measure effects of more preamble bits
+- fix activelyReceiving for sx1262
 
 ## Items to be 'feature complete'
 
 - change packet numbers to be 32 bits
 - check datasheet about sx1262 temperature compensation
 - stop polling for GPS characters, instead stay blocked on read in a thread
-- use SX126x::startReceiveDutyCycleAuto to save power by sleeping and briefly waking to check for preamble bits. Change xmit rules to have more preamble bits.
 - turn back on in-radio destaddr checking for RF95
 - figure out what the correct current limit should be for the sx1262, currently we just use the default 100
 - put sx1262 in sleepmode when processor gets shutdown (or rebooted), ideally even for critical faults (to keep power draw low). repurpose deepsleep state for this.

Have device under test send a broadcast with max hopcount of 0 for the 'mfgcontroller' payload type. mfg controller will read SNR and reply. DOT will declare failure/success and switch to the regular app screen.
