Our PCB is neither sending or receiving packets so we tried changing the clock.
- Our sending works when we changed our clock from 16MHz to 8MHz
When checking our PCB after we soldered the 8MHz clock in, we're getting somewhere between 0.4V - 0.53V for our clock, 3.3V for the Atmega, and 2.98V for our XBee
When checking our PCB when we had our 16MHz clock in, we're getting somewhere between 387mV - 720mV for our XBee
when checking our bare board with the voltage regulator, our clock is getting 0.5V and output is 2.4V
- Alicia mentioned that usually, 16MHz clocks should run at 5V and 8MHz should run at 3.3V.
Originally we wanted to keep our board at 8MHz since our board runs closer to 3.3V. However, we had trouble bootloading with 8MHz in the past.
- Due to that we resoldered 16MHz back to our PCB
We'll fix our design again so our PCB would run at 5V
So far, we know that the sending code works fine. The relay code may or may not be the problem. We'll further work with Firmware to figure out the relay code.
As a note, our range testing data may not be as accurate as we thought since the measured voltage of the clock and XBee wasn't where we thought it would be.
