Hi,

for this you can create seperate question. so that nordic employees will answer and describe the problem correctly. because if you are creating a custom service you want to specify 128 bit uuid as of bluetooth sig specifications. but you are asking to change the uuid of the service which is already implemented as per the bluetooth sig. so i am not sure about it.

Ok, great, thank you! This has been tested and works from a technical perspective. Since I'm changing the standard service, does this imply that I'm creating a custom service, i.e I ougth to set a specific 128-bit uuid?

hi,

you want to give write permission inside ble_dis.c file. some what like this

 char_md.char_props.write  = 1;

inside

static uint32_t char_add(uint16_t                        uuid,
                         uint8_t                       * p_char_value,
                         uint16_t                        char_len,
                         ble_srv_security_mode_t const * dis_attr_md,
                         ble_gatts_char_handles_t      * p_handles)
{

this function.

cheers,
