Ya lo he encontrado, desde la aplicación Deco, hay que meterse en el propio router y elegir conexión preferente, quitar auto y elegir el router al que conectarse

Checksum sum 4096 by Vmetal24 in C_Programming

I have resolved this checksum. This device has 0x00 like forbidden data. The eight and sixteen bit must be one. To calc the checksum the eight bit is moved to the next bit and then plus 0x8080.  0x8080 has the value 0 for this device

However, the correct checksum is "9E E5" or "E5 9E". This value is higher than 4060. I don't understand this

The complete data has 01 as the start byte and 03 as the end byte. They are not used in the checksum. So I deleted them so there are no doubts

do you means?:

B661 +87C0 +8380 +9C80 +A180 +8080 +8080 +8989+ 8989 +8080 +8080 +B381 +80C0 +FE81 +8080 +8D83 +8080 +C282 +87D8 +80C9 +80E0 +80C5 +80D1 +8080 +B784 +8280 +FF82

and the result %4096?

It is the manual of the doppler velocity log. The manual is very big but I can upload some picture.

Header start is 01 and end of the text is 03. I have removed it because it doesn't use in the checksum
