how to send ASCII data to MCP

[rangineni balu]

I am able to send data from EK to MCP but even i am sending one byte of ASCII(alphabet) of data, it is showing as hex value in MCP ex., 'C' as 43 , if i want to see ASCII in MCP instead of hex, how to achieve it?

Hi,

With the newest version of MCP (v3.5.0), this is possible. You will have to check the box "Display as UTF8", which is located to the left of "Read Long" button.

Best regards Håkon

yeah, its working, thanks for your reply and i tried to send 4 bytes of data byte by byte no problem, i'm recieving at usb dongle, but when i tried to send 4 bytes at a time, getting link loss

i'm attaching the MCP screen shot when it got recieved link loss error

ble_gatts_hvx_params_t params;

uint16_t len = 4;  //sizeof(button_state);
uint8_t button_state[]="NAME";
memset(&params, 0, sizeof(params));
params.type = BLE_GATT_HVX_NOTIFICATION;
params.handle = p_lbs->button_char_handles.value_handle;
params.p_data = &button_state;
params.p_len = &len;

this is only change i have done -- changing length field
