Hi All,
Currently, I changed the buffer size of mate' vm, however, I encounter the following problems:
1. using the UART to send the buffer with the size 50 seems all right, however, the send_lqi result in an error. For example, I write an program to increase the buf size every time by one and transmit it.  The UART can transmit correctly but the send_lqi will always generate an error before the buf reach its predefined max size (50 in my program)
 
2. I tested the max size I can use in my system and find that it is no more than 61, if I changed the buf size to 67 manually and run program with out sending any buf or even do  not claim a buf variable in my tinyscript, the program can not be injected into the tmote sky at all.
 
I guess the problem related to the DTOSH_DATA_LEN, it seems can not exceed 124+10.
 
Could you give me some hint for the reason?
Best Regards,
 
Song Guo
