Error "Writing is not Permitted" on iOS app for RACP characteristic

[SumitS]

Hi,

I am using the sample BLE_gls code provided by Nordic. I have made the following changes in the code:

#define SEC_PARAM_MITM 0 #define SEC_PARAM_IO_CAPABILITIES BLE_GAP_IO_CAPS_NONE

I am developing a customised iOS app. When i try to write to the RACP, i am getting an error "Writing is not Permitted".

Can you please help with this.

Thanks

Hi,

Ok. I found the issue. We have changed the BLE_UUID_GLUCOSE_SERVICE to 0x0001. The RACP is not working with this. But when i changed the BLE_UUID_GLUCOSE_SERVICE to 0x1808 its working. I am not facing this issue with NRF app on android phone. But i am facing the issue on iOS. Is there any restrictions for using a customised UUID on iOS?
