unable to increase Security level on ble services

[wasdwasd0105]

Hello,

When we tried to increase the Security level from SEC_OPEN to SEC_SIGNED_MITM, it will output error 0x6 which is "Not supported". So how can I  do to support a higher Security level?

Thank you for your help!

Hi wasd, 

Data signing is not supported in our softdevice. If you want MITM protection, please use SEC_MITM.
