- feature: option to disable wifi. Saves abt 80mA current
3 options: 2 alaways on; 1 off if no bluetooth client is connected in between
60s after boot (watch red oled button; goes off as soon as a
bt client connects in the boot phase). 0 disable (re-enabl by pressing
beacon button)
- pseudo csma/cd. ppersist / slottime as we know it from standard
packet-radio / -APRS
In loaSend. TODO: better concept with a tx-queue. But this is rather complex,
because the queue must not grow too large, else we re-send old packts..
- feature to encode altitude in compressed position instead of /A=...
compressed position can encode course/speed, altitude (and others). Option to
send course/speed to 0%, 100% or something in between.
altitude check button is obsolete. Switch off by setting alt ratio to 0.
- cross-digipeating: just for sure, clear rx queue after going back to main
freq.
- if we are not a digipeater and we have no serial-bt-client, we may let the
loraChip sleep (axp.setPowerOutPut(AXP192_LDO2, AXP202_OFF)) -> saves current
(a bit)
- adjust_cpu_freq_to: change CPU frequency. May reduce cpu power consumption
up to 20 %. Suggesting (and tested with) 80 MHz. USE WITH CARE! I.e.
40 MHz or 20 MHz did not work with my device (boot phase never ended)
- options to start tncServer and gpsServer (if you don't need them, you
may not like to expose these tcp ports to your LAN or HAMNET)
- changed preferences.getString(PREFxxxxx) to
preferences.getString(PREFxxxxx, ""), because if variable is not set,
the preferences library returns "the variable name itself" - wtf!.
In the case of PREF_NTP_SERVER, we saw log messages that ntp server
with fqdn "ntp_server" could not be resolved; it had no impact, because
it did a failback to the compiled-in default. Changed call for
PREF_WIFI_PASSWORD, PREF_AP_PASSWORD, etc.. too.
- wifi-AP: is set to esp_wifi_set_max_tx_power(8) (for lesser power
consumption of the devie). 8 dBm are too less fore some cases.
-> New web config for setting max_tx_power in AP- and STA- modes.
- Fix: In mode wifi-client, it did not reconnect if association was lost.
- small improvement for comment-text ratelimiting
BG_RF95.cpp: BG_RF95::SignalDetected feature (needed for pseudo csma/cd)
