[quote user="Juniorprogrammer"]Will this also work if I put floats in the array. Because firstly I did tryed to send a float with ble_nus_data_send, but it didn't accept it because it wants an uint8.[/quote]

Hi Sigurd,

Thanks for your quick reply.

Hi,

Put the values in an array, and then use the ble_nus_data_send() to send the values.

Snippet:

static uint8_t data_array[LENGTH];
data_array[0] = value1;
data_array[1] = value2;
data_array[2] = value3;
data_array[3] = value4;

uint32_t       err_code;
err_code = ble_nus_data_send(&m_nus, data_array, &length_of_array, m_conn_handle);
