No support for LILYGO Lora v1.4 / SX1278 not responding #346

Closed hb9tvk closed 9 months ago

hb9tvk commented 1 year ago

The latest LILYGO Lora board v1.4 is unknown and hence the autodetection is wrong.

According to the "datasheet" at

https://www.lilygo.cc/products/lora-v1-4-esp32-sx1278-433mhz

the pins are:

SX1278: MOSI: 23 MISO: 19 SCLK: 18 CS: 5 RST: 4 DIO: 26

OLED SSD1306: SDA: 21 SCL: 22

I set the pins via the hardware config (except RST and DIO which can not be configured). Unfortunately, the SX1278 is still not recognized:

Configuing SX1278FSK SPI with miso=19, mosi=23, sck=18, ss=5 0 Setting freq: SUCCESS Frequency set to 0.00 0 Setting freq: SUCCESS Frequency set to 0.00 RX LNA Gain is -999 SX1278 configuration finished

(On a working T-Beam 1.0 this looks like that: Frequency set to 402699936.00 Setting freq: SUCCESS Frequency set to 402699936.00 RX LNA Gain is 0 SX1278 configuration finished)

Later in the "sonde loop":

MAIN: Running loop in state 0 [currentDisp:0, lastDisp:0]. free heap: 136676, unused stack: 5096
0 Setting SX1278 power on FAILED Sonde::setup() done: Type RS41 Freq 0.000000, AFC BW: 500000, RX BW: 500000 TOO MUCH DATA

Tested with latest dev version: master_v0.9.2-B16-full.bin

Device: LILYGO Lora v1.4 (aka T95_V1_1)

I can compile/upload the code in platform.io, let me know if I can test/verify anything.

Ok, I got it working: Key was changing the board type to "ESP32 Dev Board" (instead of "TTGO Lora 32"), as suggested on the Arduino IDE screenshot on the lilygo page. In platform.ini, this is

[env:esp32dev] board = esp32dev platform = espressif32

I could successfully receive data from a RS41 sonde. The sensitivity of the module seems not so great though.

As this is a 'custom compiled' version, the OTA update will no longer work now (as it would install a non-working version), but that's not a big issue.

Seems like the board is not very popular (have not seen anyone else using it with my software), and there is a (manual) way to get it to work, I will close this issue and not look into how to possibly extend the auto detection.
