Hi,
I have one service UUID ffe0 that has two characteristics: one of has UUID ffe4 use for "notify" and other one has UUID ffe5 use for "write and read".
Now i want to get the data from the FFE5 and reply accordingly as per the data that I received from FFE5 suppose I write send data from mobile App to board is "SEND=1" as string to characteristic UUID FFE5 now according to the message received from the FFE5 service i.e. SEND=1 I want to reflect the characteristic UUID FFE4 as "OK" if the string matches as SEND=1. Now My main Question is How i know when the data is being received from FFE5 characteristic UUID. If I get that as an interrupt or anything I will send a reply as "OK" over the characteristic UUID FFE4.
I have also created NRF_SDH_BLE_OBSERVER for that service.
But how to get value from the different characteristics UUID like 0xFFE5 and so forth if any .
Thanks in advance.
