I am using nrf8001 for my project. The OS that I used is window8. I've got this issue when the connection is not very stable. After I connect the bluetooth module to a window 8 machine. I put the module in a place where the master need to resend 2-3 times before the slave response.(unstable connection) This issue usually occur after the master send a control opcode: LL_CHANNEL_MAP_REQ. The module disconnected before the master timeout(master timeout until connection timeout interval reached) The module returned 0x28 error code. I have set the connection parameter as follows, max connection interval :11.25ms ; min connection interval :11.25ms ; connection timeout period : 3000ms
I don't think the bluetooth modules should disconnect even the connection is unstable since it has not reach the connection timeout period. Is there are way to solve this problem?
