The version that I have is 2004 (409D5E320A), which could not work well with the TX IPV4 well.
The same code tested with xbee wifi s6, implement TX IPV4 through SPI interface, would not work with s6b.
I check the data frame that I send, which is start with 7E and following the format according to your datasheet about tx ipv4.
Since the same code works well with xbee wifi s6, I don’t think
the problem is caused by my code.
Please send me the new firmware.
Thanks a lot.
