No problem seeing long device name and connecting with keyboard sending function. So, not to be confused by the test result, I need to run all my tests with setting forget and turning BLE OFF and ON on iDevices.įor the 15 chars limit issue, I tried with nRF Connect (Nordic iOS App Tool). This table will be erased if I turn BLE OFF. Without connection or connected and forget, I program ESP32 with device name more than 15 chars and I can find the device on the list with old device name (less that 15 chars) and I can connect to it. ![]() So, I can program ESP32 with device name less than 15 chars and be found by iDevices. If a MAC exists in the table, it will skip that device and not update the information (device name) in the following scan. IDevices generic BLE scanner seems keep a table of scan result that has MAC and device name.
