GATT not supported - status 6

[Samra]

Hi I followed the Nordic UART example code to read and write characteristics to a Nordic S110 nRf51822 device.

My code is the same as in writeRxcharacteristic but when the response is returned in onCharacteristicWrite callback its status is 6 (gatt_not_supported). I am developing it for Android 5.1 and the device is xiaomi Redmi note 3

The data I am sending is a Json string

Hi Samra,

Could you add some more information on what profile you have on the peripheral. When you test with the nordic UART app do you have the same problem ? Have you done service discovery before you do writeRXCharacteristic ? Do you have bonding with the peripheral or it's open connection ?

Ok HungBui,

The problem was due to GATT 20 bytes limitation, so i was receiving the data in 2 packets instead of one single. Now it is sorted. Thanks & Cheers :)

The profile is UART and yes services are discovered correcty
