Hi all, I am facing one trivial issue while coding for BLE GATT characteristic , esp_attr_value_t ( esp_gatts_defs.h) is used in my code for pointing to values to be exchanged. I need to update a signed value , say for example : time zone of -5 hours, the attribute_value parameter in the esp_attr_va...

Thanks Lucas.Hutchinson for your comments , you have mentioned "On android phones (using the nrf Connect app) you can request an MTU change up to the max allowed by the BLE standard (517) " - Could please let me know how we could do this ? Because I see " Note: The source code of nRF Connect is not ...

Thanks mh-dev

Any way for server to increase the size of its MTU ( to be used in characteristic - attribute ) and convey it to client while connecting ?
