ADS1293: start and stop sequence

Hi,

Can you ask customer to clarify what they mean by "send start and stop sequence"?

The start and stop sequence example are described in 

datasheet page 40

"

1. Set address 0x00 = 0x00: Stops data conversion (if any). 2. Set address 0x2F = 0x32: Enables channel 1 PACE, channel 1 ECG, and channel 2 ECG for loop. read-back mode 3. Set address 0x27 = 0x01: Reconfigures the DRDYB source to channel 1 PACE . 4. Set address 0x00 = 0x01: Starts data conversion. In this case, new PACE data from channel 1 is available on every DRDYB assertion; ECG data from channel 1 and channel 2, on the other hand, is available every six DRDYB assertions (R3_RATE_CH1 = R3_RATE_CH2 = 6). There are different approaches for handling simultaneous ECG and PACE data read. One approach is to read ECG data every time that PACE data is ready, over-sampling the ECG channel. This is possible because old conversion values are retained in the data registers until new data overwrites them. A second approach is to also read the DATA_STATUS register. Continuing from the steps above: 5. Set address 0x00 = 0x00: Stops data conversion

and, this department is not BLE department if they are requesting for BLE(Bluetooth low energy) support, we don't have that expertise.

Thanks
