I'm not using nimBLE but in nimBLE I can use ble_gatt_chr_def struct which has ble_gatt_access_fn *access_cb that gets executed when the characteristic is read or written to. In Arduino I can do foo_char->addDescriptor(new BLE2902()); foo_char->setCallbacks(new foo_charCallbacks()); What's the equiv...

What example to use for NimBLE gatt server and client
I want to test out NimBLE gatt server and client. I cannot find any examples for that purpose, I have been looking at the peripheral and central examples but they are not what I'm looking for. I'm looking for example like that of BLE (bluedroid) gatt and server.
Are there any?
Thanks.

Re: How to use the NimBLE spp example?
Rahul from ESP reached out and pointed out that I can use the fields of ble_gatt_access_ctxt and the buffer om present inside this structure. So, now I'm able to read the data being sent to my ESP device.
