BLE Services and Characteristics are not shown in ESP32C3-MINI1
Posted: Tue Feb 21, 2023 10:10 pm
Hello,
I have been trying to figure out why the services and characteristics are not shown when I configure my device as a BLE Server using AT commands.
I have followed this link exactly for flashing the firmware https://docs.espressif.com/projects/esp ... le_it.html and have managed to do so. However, I have the problem I have mentioned.
To establish the Server I use the following commands:
which all return . Still when I connect to my device either via a BLE app on my phone, or another ESP32C3 device (configured as a client) I can only see the Generic Attribute and Generic Access.
All of the resources I managed to find explain how to deal with this via generation of ble_data.bin file, but this version uses mfg_nvs which also gets properly updated whenever I make changes to the gatts_data.csv file (the file that actually stores the ble data information).
Another thing to mention, if I use the command to discover the services I get returned the services from the file, but without the UUIDs, instead only 0x is shown. (I know this is the actual services and not generic ones since I were adding more services or deleting some from the csv file and the result turned out accordingly).
Any kind of guide would be greatly appreciated, because I have managed to find very little on this topic.
Thank you,
Fahira
