Unable to read all measurements on Glucose device (Contour Plus One)

Question

I am currently testing the Contour Plus One device with flutter_blue. I cannot get all the records from the device using via sample code. I have referred GlucometerBluetoothToHealthKit and try to run the commands

Examples of RACP commands (which are sparsely documented in the spec and that I had to discover iteratively):-

A) [1,1] Read all records. NO RESPONSE

B) [4,1] Number of records GETTING RESPONSE The total size

C) [1,6] Read the last record received NO RESPONSE

D) [1,5] Read first record NO RESPONSE

E) [1,3,1,45,0] Read extract from record 45 onwards NO RESPONSE

Please note I am getting the response when taking the live blood sample. I can see that in logs

The steps and screenshots are as follows:-

1. Device connected.

2. Expand Service 0x1808.

3. Press Notify option on characteristics 0x2A18.

4. Click Write option Characteristics 0x2A52 (With [1,1]) NO OUTPUT

Well, my Glucose device is having 6 records. I am not sure what I am missing here.

Also, I have noted an interesting behavior noted here when I press the sync button on the Health2Sync Android app (A complete separate app from the play store) I am able to see the output in 0x2A18 (PFA image)

I think I am triggering the wrong command to get the values. Can someone please help with the commands to get all values? I have already referred to the following articles but nothing helped
