We need to check if device #2 failed to send notification to device #3 or it's device #3 receive the packet but don't send the app a call back. You may want to use the sniffer for the purpose.

Also check if the hvx command return NRF_SUCCESS when you call it.

Device#3 is nRF Connect App. From Device#2, I send HVX notification using the command ble_lbs_on_button_change() from lbs service.

In Device#2, I check for notifications. In App - also I wait for notification. When Device#1 disconnects from Device#2,I get notification "BLE_GAP_EVT_DISCONNECTED" then start scanning.

Hi Raju,

How do you send message from #3 to #2 and from #2 to #3 ? Do you use notification or you use write command ?

How do you check if you receive the packet or not ? Do you do anything when #1 disconnect ?

Could you capture a sniffer trace on the communication between #2 and #3 ?
