Hello,
I am facing connection issues with the CC2541. Indeed, after being able to connect/disconnect 159 times from the CC2541, afterwards, it is no more possible to connect to it until a reset is done: I've checked BLE packets using TI BLE sniffer and saw that a connection is made but the CC2541 never answers ATT requests (successful connection and failed connection sniffer traces are attached).
I saw on other posts that this could be due to SNV corruption thus I compared CC2541 flash before and after failure: both FW images are the same. It thus doesn't seem to be related to SNV.
I am running out of ideas and really need your help on this issue since it seems related to the BLE stack (connection accepted but higher protocol level requests never answered).
Important information:
- The BLE stack used is 1.4.1.43908
- The device is in Peripheral mode only.
- The device has 8 custom services and 21 custom characteristics in total.
- POWER_SAVING is not used.
- After the issue occurs, the device is still working when BLE is not "connectable" anymore.
Thank you in advance for your precious help.
Best regards,
Johann
