I am trying to use BLE to send strings of data from a CSR8675 chip to an iPhone
I am having problems pairing the chip with the iPhone for BLE communication, and need some ideas on how to proceed with troubleshooting
Normally if a bluetooth device is properly connected to an iPhone, in the bluetooth settings window it will be shown as connected with a blue i inside a circle
However, my device is only shown as connected and there is no i inside a blue circle
At some level, the CSR8675 chip internally considers itself connected to BLE (I know this because if I enable debug messages for the program I am running on the chip, I can see a timer that periodically checks for bluetooth and IO pin activity show a message that BLE is connected)
However, if I try to send bytes from CSR to iPhone or from iPhone to CSR, it doesn't work due to absence of BLE connection, but both devices consider each other connected
I would like to know what it means when the iPhone shows connected without the i symbol. Are there multiple reasons that can cause this? Any help is appreciated.
