Hi,
I got some Moteinos and soldered the RFM69CW / 868 Mhz modules myself.
I chose these because of the RFM12B compatible footprint that I use in other projects.
I wrote some code based on the Node example and successfully transmitted data from one moteino to the other.
But:
1.
I have to enable #define IS_RFM69HW so radio.setHighPower(); is called.
But this is not a HW module. It is a CW module.
If I dont call the setHighPower() the modules don't see each other at all even not when they are 1 cm away
2. When they see each other it is only for ~ 1-2 Meter distance
If i move them further away from each other they don't see each other anymore at all.
The usual RSSI is -79 !
I checked the antenna length (82mm).
I checked the power supply to the moteino (5V over FTDI) and 3.3V at the module side from the onboard voltage regulator.
I did read a lot of forum posts on this forum and a german microcontroller.net thread, but could not find anything to solve my problem so far.
This project will be an open source game and it will be way awesome. Please take a minute to help me out if you have any idea what is going on.
Thank you in advance.
Thank you
