Support for heltec wireless tracker. And many fixes. Two weeks hard work. - Webserver config: - Allow freq to be configured down to 430.1000. Set to at minimum 430.150 if you use bandwith 250 kHz! - Added hint for wifi tcp kiss android config - platformio.ini: - less monolithic lib dependencies, because with heltec wireless tracker we have another radiolib and a TFT instead of OLED, no AXP chip, etc. - heltec section: need to have the many defineshere (two hand full are needed for TFT) - heltec wireless tracker: - long press (if WiFi off) sets the tracker to deep sleep (there's no real power-off due to the lack of an axp chip. But the current is very very low). See also notes at webserver config. - uses RadioLib SX126X - has no AXP chip, and the VEXT_CTRL pin only switches (both at the same time!), gps and tft. For power saving ("lora rx disabled" config setting), we can call radio.sleep(), and wake it up with radio.standby() - If you set gps to allow sleep, VEXT_CTRL turns also TFT. Be aware of it, it's not a bug but a hardware limitation. GPS sleep is for powersave. TFT off saves also power. That's what you should expect. On wakeup, tft is reinitialized. - Funny: If you do Serial.flush() and immediately call setCpuFrequencyMhz(adjust_cpuFreq_to), then USB chip is reset to a state before that what the esp32 driver inizializes. -> Serial.printf's don't work. This lead to Serial.print("CPU Freq ad"); Serial.flush(); setCpuFrequencyMhz(adjust_cpuFreq_to); // ..survived Serial.printf("justed to: %d MHz\r\n", adjust_cpuFreq_to); -> "CPU Freq ad" - and finito. => removed the flush() - TODO: bluetooth LE support. Unfortunately, the chip lacks support for classic bluetooth serial. If you need to connect aprsdroid to the device, look at the wifi tcp server description. - TTGO_T-Beam_LoRa_APRS.ino: - better platform dependend includes - I had a bad usb cable or switch with too less voltage which caused the ttgo to reboot -> Changes to minimum voltage for shutdown Disabled brownout detector (which was per default according to esp32 libs) WRITE_PERI_REG(RTC_CNTL_BROWN_OUT_REG, 0); Please check if this would be a problem of deep discharging your akku: #if defined(T_BEAM_V1_0) \|\| defined(T_BEAM_V1_2) - if (InpVolts > 4.3) { + //if (InpVolts > 4.3) { // No, my usb hub suddenly only made 4.1V + if (InpVolts > 4.0) { I suppose no, because AXP does it's job at thosee devices - Needed to define BATTERY_PIN for every hardware - Renamed definition of LOW to TXLED_LOW - What is key_up, t_lock and time_delay? Wrong, it's for button control. -> Changed the names to button_key_up, button_t_lock and button_time_delay - LORA_MAX_MESSAGE_LEN is for SX127X (B_RF95 lib), because it includes the 4 bytes header. For the RadioLib buffer we need to reserver more space. - quite nice hack for reusing the display.xxx() routines for tft (class Emulated_SSD1306 which provides the needed functions) - New OLED_LINE_LEN_MAX instead of hardcoded value 21, because heltec TFT has in the normal font a width of 25. - RadioLib calls interrupt drivven signal_new_packet_received after a packet was receeived. - RadioLib special: Added definition for lora speeds / coding rate, like they have been addigned in the BG_RF95 lib - Pseudo-Sema-Locks: does not work 100%. Avoided endless loop by adding ESP.restart after 5min Also a delay of 1s in LoraSend() to mitigate lock problems when digipeating to the second of the both frequencies. - BG_RF95 sometimes causes crashes, esp. in waitPacketSent(). Introduced a delay. 100ms between sendAprs() and waitPacketSend() Changed calls to rf95.waitAvailableTimeout() to rf95.available() for stability reasons. - richonguzman has a good docu for power readings for non-AXP-chips. I use it for the heltec wireles tracker We may think about using it on T_BEAM_V0_7 and the rest. Problem: intensive testing needed, and the old T_BEAM_V0_7 devices became rare. - timer_once_a_second(): This is ok: if (!freeze_display) fillDisplayLine1(0); //update time & uptime But the following operations destroyed line3to5 for a displayed "((RX))" packet. -> Commented it out. No side effects observed-. - write2display(): now uses caching (calls write2display_cached()). Reason: TFT flickers when updates happen too often. On the other hand, caching on OLED is not possible because calling display.clearDisplay() is mandatory, else you get a pixel puzzle with old and new characters at each position. TFT has no display.display() and also nothing like clearLine. -> IF we write a line, we have to add (when using the normal font) blanks at the end of the text (up to position 25)-. Also, instead of OLED, TFT cannot brak long lins to the next; that's why we need to break the line ourself. The "next" lines we use in this case must not be cached. - fillDisplayLine1: Word "Up:" was behind the uptime value (caused by one of the commits of the last weeks). Fixed. - If own callsign is still N0CALL, disable lora_tx and set txPower to 0. - If during setup init lora chip or display fails, do not for(;;); , but sleep 5min and do ESP.restart(). Else you cannot land on the moon ;) TODO: check for correct initialization of SX126X chip - Removed tuplicate "Time used since start"-message - start of taskGPS moved to setup_phase2 section - If you double-click (or better "dit daah") the user button, manual beacon is triggered (like the behaviour at the end of the section). Needed by someone driving a car and cannot look at the display menu page number. - long press (if WiFi off) sets the heltec wireeless trackeer to deep sleep (nearly off - see description above). If wifi is off, press two times (first long-press starts webserver; second one does the shutdown). If tracker is not compiled with WIFI, long-press does a shutdown on heltec and a a reboot on other devices. TODO (and TEST!): check if other non-AXP-chip esp32 devices would instead also profit from a deep sleep - Tests before radio.readData() on SX126X devices are easier (no locking; no call comparing to rf95.available()), because flag_lora_packet_available is set. Changed general variable name packet_available to flag_lora_packet_available. - In part "((TX))", enforce a display update: fillDisplayLines3to5(1); Reason: tracker had his first gps fix and transmits - but the OLED showed the old position during TX; the sent packet hat the correct current position. - taskGPS: - support for heltec wireless tracker (Pin assignment and correct bitrate) - fix: - Serial.println(gpsDataBuffer); + Serial.print(gpsDataBuffer); - taskTNC: - if (serial_bt_client_is_connected) { + if (enable_bluetooth && serial_bt_client_is_connected) { - taskWebServer.cpp: deadlock protection, as in TTGO_T-Beam_LoRa_APRS.ino - data_embed: style.css and js.js had many blanks and comments which needed a quite large amount of disk space. A new script ../tools/remove_comment_from_code.py (which also can be used as a library) removes them, but leaves copyright comments intact. Feel free to use it in other projects.
