Send command BLE and notifications Quectel MC60 BT Client

Good morning.

I have a pulsioxymeter which has a service with two characteristics.

If I send the command “AA14EB00000000C6” to write feature from my mobile, the Pulsioxymeter responds me with general data:

Now I need to replicate exactly this but using Quectel MC60 Bt.

I have followed all the steps in the datasheet and I able to scan near devices, connect to my pulsioxymeter, list and check every services/feature, register to recieve notificacions and send the command to see the general data but in this point I don´t recieve data/notifications like in my mobile.

Here is my log from quectel:

When i read the value of the descriptor it is “0000” when it should be “0100” that is the value that i wrote in the previous step.

Thank you for your time and help.

Does anyone have any ideas?

It was problem with datasheet and configuration of the client.

Hello @Javier,
I’m happy that you have solved that problem. I have the same issue. I can send commands to my BLE device but I do not get any response (except the usual response of the AT command). Could you please tell me what the problem is in the datasheet and how I can solve this problem?
