CoreBluetooth With BLE stopping read after a while

Could you show more code, notably how and where you call readValue ?

From doc

This method is invoked when your app calls the

readValue(for:)

method, or when the peripheral notifies your app that the value of the characteristic for which notifications and indications are enabled (via a successful call to

setNotifyValue(_:for:)

) has changed. If successful, the

error

parameter is

nil

. If unsuccessful, the

error

parameter returns the cause of the failure.

Thanks for the help.

This is where I'm reading from

func peripheral(_ peripheral: CBPeripheral, didUpdateValueFor characteristic: CBCharacteristic, error: Error?) {

if ((error) != nil) {

print("Error didUpdateValueFor: \(error!.localizedDescription)")

return

}

if peripheral.identifier != bleperipheral?.identifier { print("GOT DATA BUT NOT FOR ME"); return }

switch characteristic.uuid {

case SMASHTAG_DATA_UUID:

if let data = characteristic.value {

Data += data

Etc etc.

Its reading fine, but then just stops.
