NodeMCU/PICO W with SX1262 #1

Open Jaishankar872 opened 6 months ago

Jaishankar872 commented 6 months ago

I built two lora system with below configuration.

  1. NodeMCU+ SX1262
  2. Pico W + SX1262 Now, I want integrated with ESPHome with External Components.

To start with I want to first send your text message between this two devices. I tried using your code, but it is not working for me. I have fewer following doubts.

  1. Reconfig SPI pin for the MCU
  2. How to check SPI communication is successful (I couldn't see debug print from the function void LoraSX126X::setup() )
  3. How to port this for other ESPHome like NoduMCU, PICO W

I am newbie to ESPHome, your support will greatly help for me.

Thank you in Advance!!!!!!!!!!!!!!

Sorry for the delay.. could you please post links to specs for these two boards?

Thanks for your response @PaulSchulz

  1. NodeMCU + SX1262

    Here I used NodeMCU board with SX1262 XXXM LoRaWAN/GNSS HAT from Waveshare (https://www.waveshare.com/wiki/SX1262_XXXM_LoRaWAN/GNSS_HAT)

GPIO14 -> SCLK pin GPIO12 -> MISO pin GPIO13 -> MOSI pin GPIO15 -> NSS pin GPIO16 -> DIO1 pin GPIO4 -> NRST pin GPIO5 -> BUSY pin

  1. Pico W + SX1262 Here I used the Official Raspberry Pico w with Pico-LoRa-SX1262-868M from waveshare(https://www.waveshare.com/wiki/Pico-LoRa-SX1262-868M#Hardware_Description)

Note: Both hardware I tested using the Radiolib library in Arduino

After this build the new 2 identical setup which explained in this issue (https://github.com/PaulSchulz/esphome-lora-sx126x/issues/2)

I think this could be related to my problem as well. #3

Hardware is different, but this is the same for me: I couldn't see debug print from the function void LoraSX126X::setup()
