discover services on s1xx-iot-prototype2_softdevice reports READ_NOT_PERMITTED

[Achim Kraus]

Hi,

I tried the nrf51_iot_sdk_0.8.0_f1f6187 and flashed the coap example (examples\iot\coap\ipv6\client\boards\pca10028\armgcc) with the s1xx-iot-prototype2_softdevice on my PCA10028. I could communicate with a linux bluetooth_6lowpan, so there should not be too much wrong.

But using your Master Control Panel 3.9.0.6 (with MEFW 0.11.0 or with 0.9.0) to "Discover services" on the device reports "READ_NOT_PERMITTED".

The examples are not made for communication with Master Control Panel. Why do you want to use it? In addition to the Generic Access service and the Generic Attribute service the GATT server will include the Internet Protocol Support Service with no characteristics. This is only used to discover if IPSP is supported or not, not to exchange data.

Hi Petter,

thanks for you answer.

The examples are not made for communication with Master Control Panel. Why do you want to use it?

I just want to "discover services" and therefore I used the "Discover services" function of the Master Control Panel. I was just irritated by the reported error.
