RE: getting gatt error while uploading the firmware over ota

Hi,

Error 133 (0x85): GATT ERROR is an generic error, it happens in different occasions. We have observed it on:

1) Packet collision
2) CONNECT_REQ missed by the target
3) Timeout (30 or 20 seconds after connection was initiated)
4) in general, an expected packet wasn't received or an unexpected was.

It used to be much more common in the old days, now we see it less and less with the new phones, but the low-end devices might see this issue.

What phone model/brand are you using ? Do you see this issue on several phones, or only on one phone ?

Hi,

Have you tried using the debug variant of the bootloader(pca10040_ble_debug), and see if you get any errors or asserts printed in the terminal?

PS: If you are having issues with the RTT logging, then you might need to set NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED in sdk_config.h to 0
