Hi all !! 

I had trouble updating my ACEMATE Tennis Robot S10 because it was still running firmware version 1.2.2.

I tried using an iPhone, an Android phone, and a Chromebook tablet, but none of these devices could detect the ACEMATE hotspot or Wi-Fi network. As a result, I could not connect to the robot or install the firmware update.

It seems that, with older firmware versions, the robot may have difficulty determining its location or confirming the selected country or region. In my case, I was in France, but the robot apparently could not identify the region correctly, so it would not create the hotspot required for the update.

 The solution was surprisingly simple, although a little unusual:

I took the robot into town and placed it near an apartment building where many Wi-Fi networks were available. I then repeated the connection and update procedure.

Once the ACEMATE detected several nearby Wi-Fi networks, it seemed to recognise that it was in France, or at least in the country selected in the app. The ACEMATE hotspot then appeared normally, and I was finally able to connect to it and complete the firmware update.

So, if your ACEMATE hotspot does not appear, try moving the robot to an area where many Wi-Fi networks are visible, such as near apartment buildings, offices, or a busy residential area. Then restart the robot and repeat the hotspot connection procedure.

This may be particularly useful for ACEMATE robots running firmware versions older than approximately 1.3.7.
