Thanks so much. I tried 2000 first and then decrease it to 1600, is there any way to caculate which value is suitable?</p><div style="clear:both;"></div>RE: S112 returns 0x04 error code when use sd_ble_gatts_service_add to add service UUIDhttps://devzone.nordicsemi.com/thread/116404?ContentTypeID=1Mon, 08 Jan 2018 16:34:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:28c623c9-a340-427c-8fd0-c1b018e2ad30Petter Myhre<p>Have you tried to increase the attribute table size?</p><div style="clear:both;"></div>
