Hi Andy,
The latest firmware you are using is still not reliable as I met the same error as you. You may try this: The data length you send to the rfbee should be the same as the threshold every
time, otherwise, the receiving rfbee will receive invalid data endlessly. (However, it does not happen on Hans)
If just control PD5 and PD6, I think firmware v1.01 is no problem, and you may need to do some small changes in the ISR receiving function.
Yes, firmware v1.1 has much free RAM than v1.01 or v1.03, and the structure is more clear. However it is not steady now.
Yes, the data perestored to the EEPROM is different.
Use SVN you can get different versions(latest or older) from branch.
seeed is trying to do more open source project, and we are glad to hear any suggestion or advice to make the platform much better.
May this helpful to you, and feel free to ask any question!
