code: for loop with diff chunks sample provided in above

const dataBytes=Buffer.from(chunk, 'base64').toJSON().data; console.log("dataBytes", dataBytes); // console.log("length", dataBytes.length);//336

            BleManager.writeWithoutResponse(peripheralId,  "0000xxx-1809-2101-1357-65626173746F","0000xxxx-1809-2101-1357-65626173746F", dataBytes,20,2)
            .then(() => {
                console.log('Write operation successful');
                this.updateCounterData(index,totalChunks,peripheralId)

            })
            .catch(error => {
                console.error('Error during write operation:', error);
                // Handle error
            });

xcode log :

can you provide me solution i'm getting always console.log('Write operation successful'); but it is not working in iOS

android getting E (4324007) NimBLE: ble_hci_rx_acl failed to allocate ACL buffers; increase ACL_BUF_COUNT

It appears that the feature does not support writeWithoutResponse

[PrudhviBanki]

Any solution for this?
