Unable to update Connection Parameter

[Deepak Kumar]

Hi all,

I want to update my connection parameter as follow:

 #define MIN_CONN_INTERVAL                MSEC_TO_UNITS(7.5, UNIT_1_25_MS)      //400     /**< Minimum acceptable connection interval (0.4 seconds). */
#define MAX_CONN_INTERVAL                MSEC_TO_UNITS(40, UNIT_1_25_MS)     //650      /**< Maximum acceptable connection interval (0.65 second). */
#define SLAVE_LATENCY                    0                                          /**< Slave latency. */
#define CONN_SUP_TIMEOUT                 MSEC_TO_UNITS(7000, UNIT_10_MS)  

however I am not able to do that. update is only possible if I put my MIN_CONN_INTERVAL = 24.

Please help me figure how to set my update connection parameters as below MIN_CONN_INTERVAL = 7.5 MAX_CONN_INTERVAL = 40

thanks!!

With Apple devices the Bluetooth Accessory Design Guidelines for Apple Products must be followed.

See section 3.6 for connection parameters.

Hi Petter, My device is not specific with apple devices only. I want to connect it with Windows and Android also. iOS devices cannot accept 7.5ms but Android and Windows may accept this connection parameter. Is it possible to update my connection parameter with a specific number, say 7.5ms or 10ms, separately without considering about the range in MIN and MAX connection interval.  (I can give the MIN and MAX connection intervals as 7.5 and 40)
