I’ve setup the duo to properly take in arudino sketches and updated the firmware to be compatible with 0.3.2 of the board in arduino as well as the firmware itself. After uploading the BLEController sketch to the duo, I tried communicating with my custom app to the duo and it receives the messages from the app but the app doesn’t receive messages back from the duo.
Likewise, when using the provided BLEController app from the app store, it scans the duo but upon connection it displays “Error: No response from the BLE Controller sketch”, which is consistent with my custom app as well.
Is there something wrong with the
memcpy(characteristic2_data, buf_tx, 4); ble.sendNotify(character2_handle, characteristic2_data, 4);
sendNotify function or is something else going on?
The arduino console outputl log:
BLEController demo. BLE start advertising. Device connected! value: 56 Disconnected.
Device: iPhone X
Arduino RedBear Duo Board: v0.3.2
Thanks for any insights people can provide.
