Adapting pinning/configuration NRF24 modul to openDTU

[pade1984]

hi together,

I need your help. I flashed openDTU and want to adapt the config.json file for the pinning of the NRF24 modul. The NRF is connected to following pinning

• CSN GPIO 5
• CE GPIO 4
• SCK GPIO 18
• MOSI GPIO 37
• MISO GPIO 19
• IRQ GPIO 16

I used the attached config file and restored it in the configuration in the UI. After that openDTU is not connecting anymore the the network.

nodemcu_esp32.json

Can someone help me what I am doing wrong?

Thanks

Phil

Hi,
After restoring the pin configuration, did you set the correct profile: "NRF24" under Hardware (Hardware Settings) > Connection Settings?
Sometimes the openDTU needs a hard reset: briefly disconnect the voltage.
What do you mean by: openDTU no longer connects to the network? Is WiFi no longer working?

Edit:
You closed this discussion, what was the solution?

On my OpenDTU's the standard pin for mosi is GPIO23 !! not MOSI GPIO 37 ?
Also i can not find GPIO 37 , see attached picture for an 38PIN ESP32 !

Hi,
You're right: the pin doesn't exist, my mistake.
Pin 23 would be the correct pin.
There is something wrong with your nodemcu_esp32.json.
Wire the radio module as indicated here.

Use this device profile: nodemcu_esp32.json
Then everything should work.
