Hi All,
I use ble_app_blinky example and Android nRF Blinky SDK to add new function.
Recently, I add a new characteristic and use sd_ble_gatts_value_set() to set JSON format string.
On Android APP side, call readCharacteristic(mCharacteristic) API to read the JSON string.
It works if the JSON string less than 512 bytes.
I know that the p_value of the function packet format of sd_ble_gatts_value_set() is 0~512 bytes. (0xA5-sd_ble_gatts_value_set).
I think I need to break the JSON string into multiple packets to avoid p_value more than 512 bytes.
but I have no idea how to do multiple packets and let APP call readCharacteristic(mCharacteristic) API one time to get all packets?
Is there any example of sd_ble_gatts_value_set() more than 512byes or any suggestion?
Thank you,
Tim
