how can I unpair/reset Complete?

[iPsych]

My Complete is not able to peer mac or even iphone app. in mac, I faced with below error.
Any specific way to 'hard reset'?

Sorry, I do not have experience with mac os. If there is any option in the system settings to remove paired bluetooth devices, I would give this a try.

When you say that it does not peer with the iphone app, do you refer to the official "omron connect" app in this case? At least on android it has an option to redo the initial pairing with the omron device.

Did you put the omron device into pairing mode (blinking P on lcd) while you attempt to connect for the first time on your mac?

@userx14 Thanks for quick reply.
It seems it's not mac side issue. It seems HEM-7530T can't 'forget' previous connected device. Any 'hard way' to reset device or jumper-level trick for omron HHXMD05T bluetooth module?

[userx14]

I think the IC on the bluetooth module is a toshiba TC356xx bluetooth chip. I'm not sure which operation mode Omron uses, but there is one mode were the main bluetooth stack runs on another microprocessor, and the bluetooth chip just recieves HCI messages. So it is possible that the pairing information is stored it the external EEPROM that is connected to the main processor and not on the bluetooth module.

I did not encountered such an issue before, can you test if this problem also occurs with an android or windows device?
Could you provide some details, on what happened before the pairing stopped working?
