multiple characteristics from LBS example

[Sébastien Schiesser]

Hi,

Starting from the LED Button Service found in SDK_12.2.0/examples/ble_peripheral/experimental_ble_app_blinky I'd like to add two characteristics on this service. I used this post as a starting point, replacing the ble_lbs.c/.h files in my current SDK and modifying some lines of the main file.

It looks like if everything would work until I press the second button which should send an integer: the application resets!

I tried to debug but can't see anything anormal until the debug pointer arrives to return sd_ble_gatts_hvx(p_lbs->conn_handle, &params); and then disappears...

Do I make such a common mistake that someone can explain me what I should modify? Or help me to provide some more relevant information.

Thanks, Sébastien

Have you seen this? I guess sd_ble_gatts_hvx() returns an error, not 0x0? And you APP_ERROR_CHECK() does a reset?

Thanks Petter for the advice. I got the error code 0x3401 (missing system attribute information) and followed this link to update the stack on CONNECT. The 2nd button doesn't cause any error anymore, but nothing arrives to the receiver yet... looking on the receiver side for some issue.
