Increasing number of bytes in HID descriptor

[bscdb]

Hi,

I'm working on hid keyboard example. How can I check whether multiple bytes are received & transmitted after I increase the assigned no. of bytes in input/output report? From the code I understood that nrf device can send 64 bytes to host device. So how do I append bytes in one packet of 64 bytes when sending to host? How does it work from host side? Does nrf read 1 byte at a time sent from host?

I hope that I found the solution for BLE hid keyboard example and increase endpoint out len to reach 64 bytes.

I post here all the diff:

//#define NRF_SDH_BLE_GATT_MAX_MTU_SIZE 23

#define NRF_SDH_BLE_GATT_MAX_MTU_SIZE 96

 //       0x95, 0x02,       // Report Count (2)

0x95, 0x14,       // Report Count (20) //was Report Count (2)

//uint8_t  report_val;

uint8_t  report_val[64];

//STATIC_ASSERT(OUTPUT_REPORT_MAX_LEN == 20); // was == 1)

//#define OUTPUT_REPORT_MAX_LEN               1 

#define OUTPUT_REPORT_MAX_LEN               64

Is this all correct?

Now is working in linux (ubuntu) with:

sudo ./hidapitester  --open-path /dev/hidraw3 --length 0 --send-output 0X1C,0X00,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2

The data reach the Nordic NRF52840 with the softdevice S140.

Best regards,
