Hi, There, I use 52832 to develop a HID touch(single point) device, it can work on android & windows, but can't work on iphone13(ios15). It can connect to iphone, but no touch effect.
Any suggestion would be great help. thanks.
Here is the report map:
uint8_t touch_rep_map_data [] = {

the default gap parameters are used:

#define SLAVE_LATENCY 20
