TTGO T-Beam looping

1

Hello,

I own two TTGO T-Beam version V1.1 boards and I am not able to make them work. The problem I encountered is while trying to read the EUI code (meaning I try to load the TTN DeviceInfo example) the rebooting… endless loop appears.

Rebooting...

What should I do ?

P.S. I am using Arduino IDE on Windows 10. I am able to see both devices and I can successfully run the search wifi example. I also tried to change the USB cable but there was no difference. Should I try to power externally via a power supply and then connect to the pc? (I’ve read that the voltage can be source of this problem but I’m not sure if I can power externally and also plug the usb into the pc).

The TTN libraries are created for nodes using the Microchip RN modules which are not present on the TTGO nodes.

You need to use a different code base for this hardware. Take a look at the Big ESP32 + SX127x topic for options.

Thank you, I’m reading about it at the moment. Here should I also find a way to read the EUI code ?

You will probably find information on the availability of an EUI as ESP based board might not have an EUI as such.

6

Could you solve it @danielbalca? Same problem over here

Which problem - using the wrong library or no EUI?
