Other Parts Discussed in Thread: CC2541

Hi, R&D,

I meet the problem that the connected BLE is disconnected abnormally when flash earse, it will result into the oad always fail.

It only happen on the android phone(oppo find7, huawei ascend p6 etc)

I config the min interval 20ms max interval 40ms slave latency 0 supervision timeout 6s

how to resolve it?

Hi Michael,
A Flash page erase takes 20 ms. In that time the CPU is not able to process a connection event.

Are you using the OAD service in the BLE stack 1.4.0 on CC2541?

Hi Michael,
You should try increasing the connection interval to min 40 ms to see if the issue goes away.
