Hello !!! I will like to build my own LoRa Node Device with esp32 Wroom chip and one RFM95. P2P was successful but now i whanna active ton the TTN. Can someone help me on this project ? i am over than one week on this but i cant send any information packet to the TTN Consol. Thank you for advance …

P2P requires different signals of the RFM95 to be connected to the controller. Please provide more information in the hardware (circuit diagram would be helpful) and what software you are trying to use.

I am using ESP32 Wroom chip (witout development board). I am trying to use the examples from TTN and TT Message libraries. As for the circuit I connect RFM95 ESP32 Wroom chip MISO MISO MOSI MOSI and i dont know the rest. Is posible to use ESP32 Wroom chip with RFM95 as node >?

Yes possible I plan to do the same. Have a look to ct.de/y7yx to how to connect the RFM95 and what library they uses. They just connect it to simple Prozessor but you can do same with Wroom. Or have a look to Adafruit Feather M0 with RFM95.

@piperidisalexandros for full communication between RFM and processor you should also connect the CLK and NSS signals.And then I don’t know what stack you are using, but most stacks also use DIO0 and DIO1 from the RFM to signal TX-complete and RX-complete/RX-timeout events.

I am using the following connections RFM95 ESP32 Wroom GND--------GND 3.3v--------3.3v DIO0--------D13 DIO1--------D12 MISO--------D19 MOSI--------D23 SCK--------D18 NSS--------D14 RESET--------D27 The code is: /************************************************************************…

Ok i will do that. Thanks for advice. Did you know how to make LoRa End device with only one microcotroller ESP32 (Chip not development board ) and RFM95?

[image] piperidisalexandros: Did you know how to make LoRa End device with only one microcotroller ESP32 (Chip not development board ) and RFM95? Its straightforward enough, you can simply use an external serial adapter to program it. Its really going to need a PCB designed to take it though. …

The idea is to make a collar for wildlife. more specifically about deer. I want to know their exact locations and pass them through the TTN. I’ve solved the issue of how to program the microcontroller. The problem is how I’m going to connect the chip into the module in order to active it .
