Important note – Warning<\/h3>\n

\"\"Attention<\/span> :\u00a0<\/strong>This tutorial is proposed for educational purposes. It details technical steps to reconfigure equipment labelled Anytone ATD-868UV<\/strong> V2 GPS to an equivalent Anytone ATD-878UV<\/strong> GPS equipment.\u00a0 This requires precise handling of the hardware and software. Be very careful and rigorous. Apply this tutorial only if you have the necessary technical knowledge. After this modification has been applied, the manufacturer will certainly lift any warranty on your equipment. The author of this article cannot under any circumstances be held responsible for any malfunction of the equipment, loss of data, or any consequence of the implementation of all or part of the information made accessible by this Internet blog.<\/p>\n

Purpose<\/h3>\n

\"\"<\/p>\n

After its ATD868UV<\/strong> version, Anytone released its ATD878UV<\/strong> version in mid-2018. The main evolution of this latest version of the DMR walkie-talkie is its APRS function for analog channels, in addition to the APRS on DMR channels. After analysis, we realize that the two electronic platforms are identical. In any case, the V2 version of the ATD868UV<\/strong> is the same as the ATD878UV<\/strong>.<\/p>\n

It should also be noted that the BTECH DMR-6X2<\/strong> model, which is the equivalent of the AnyTone AT-D868UV<\/strong>, can also be modified under the same conditions.<\/p>\n

Which version of the handy can be transformed?<\/h2>\n

Indeed, there are several hardware versions of the ATD-868UV set. Only version 2 is compatible with this modification.<\/p>\n

On the identification label on the back of the radio (under the battery), you will see FCC ID: T4KD868UV. But this indication is the same for all versions of the set. This does not allow to know if the terminal is compatible with the update. Similarly, the hardware version indicated in the Info menu is in any case indicated V1.10. The only way to be sure that this corresponds to a V2 device is to check the reference of the ARM processor.<\/p>\n

The ATD878UV software uses about 750 kilobytes of memory. The ARM processor of the V2 version is a GD32F303VG<\/strong>T6 with a 1024 kilobyte flash memory. The GD32F303VE<\/strong>T6 processor integrates only 512 kilobytes.<\/p>\n

Nevertheless, the serial number printed on the back (S\/NO) may be a good clue. But we do not know exactly the number from which the items are in version V2.<\/p>\n
