RAK7204 Not able to use

LPWAN Modules / EVBs RAK811

Nice to know it is working now. Most likely it is the cable :slight_smile:

Also, you donā€™t need to reflash it. It should work right out of the box.

Thank you @carlrowan hinting me the 3.3V, I have made additional investigation and it seems that real problem was that the battery of RAK7204 wasnā€™t correctly connected. So one has to be sure that it sticks correctly and device is operating before it is connected to USB. W/o battery correctly connected it behaves as described above.

Hello ,

I recently bought a new 7204 Weather Sensor.
Out of the box it has 1 jumper installed only .
Is that correct?
Also , trying to set it up for Helium Console and when getting the EUI keys etc in Serial Port Tool all Iā€™m seeing is the error messages : ā€œtoo few parametersā€
I have no idea what that means .
Has anyone seen this ?
Thnx , Michael

Hi @StJam Yes, only one jumper should be on the PCB.
Can you show what command you issued before getting the error?
