what hex value to be written on the the MCP (immediate alert service) for IOS

Hello Everyone,

I have been working around BLE profiles for few months and i have made several tested for each service via MCP(android) everything works fine but now i switched to IOS(MCP) when i connect for the first time it is asking static passkey and then its get connected and bonded when it comes to writing values like for an example am using immediate alert service when i press the write button it is asking me to write the hexadecimal values so i wrote 0*01 for mild alert but nothing happens in the NRF51DK the same functionality if i do in Android it makes the LED ON the Developement board so i request anyone could you suggest me how to test the proxmity service and immediate alert service in the IOS MCP do i have to make some changes in the functionality of the program or please tell me what needs to be done

Thank you prabhu

    After that the LED3 on the nRF51 DK light up.

    Please provide us a sniffer trace capturing packets when you are testing. Also please run in debug mode and check if there is any write event.

  • Thank you so much for your kind reply yes you were right after the first bond then i disconnected and trying reconnect with theNRF51DK device but it wont function or receive any information from the IPhone NRFMCP and NRF TOOLBOX , but its completely oppoiste it is working very well on the android phone NRFMCP/NRF TOOLBOX, am also thinking in the same way how can i store the bonded information do i need to add any external functions or what should i do for that issue?

    I have also tried the proxmity example on the NRFTOOLBOX by using IOS its got connected for the first bond after disconnecting for the first time and while reconnecting again the device is not at all functioning and moreover all the examples are like that for the first time it is asking for pairing then we need to delete or erase the bond inforamtion for future connectivity could you please try on your side with your iphone you too were facing the same issue like me for reconnectivity
