Yes, you need to qualify/list any product that uses BT SIG intellectual property, even if you do not use the logo or require interoperability with other BT devices. see here for more details. Qualify Your Product | Bluetooth® Technology Website

 

In general, cleaning the populated modules is strongly discouraged. Residuals under the module cannot be easily removed with any cleaning process. 

• Cleaning with water can lead to capillary effects where water is absorbed into the gap between the host board and the module. The combination of soldering flux residuals and encapsulated water could lead to short circuits between neighboring pads. Water could also damage any stickers or labels.
• Cleaning with alcohol or a similar organic solvent will likely flood soldering flux residuals into the RF shield, which is not accessible for post-washing inspection. The solvent could also damage any stickers or labels.
• Ultrasonic cleaning could damage the module permanently.

However, if water washing is required you will need to use deionized water. We do not recommend chemical cleaning and cannot guarantee it will not damage the modules. If you MUST clean PCB with chemicals it is recommended that you test on one board and then confirm the module still works after the process, prior to adding it to production, while understanding the above affects washing the populated PCBs can have on the module.

Question: I have a working project on a custom board that contains the SaBLE-x chip. The software used TI's 2.1 stack. Now, we need to support BLE 4.2 protocol so the question is: Can TI's 2.2 stack be used with the SaBLE-x. If yes, do you have any instructions?

Answer: Please refer to the following resources.

Actually the extended range is achieved with slower transmission bit rate which let the radio emissions can be correctly received at a longer range. This data rate is reduced.

Q: I'm developing a BLE connectivity solution for a specialized device that needs to be operated via smartphone (iPhone and Android) using the BL652 module.  I am working with the programmer on the smartphone application side. Where can I find the source code for the ModuleLink Application for Android/iOS to accelerate the development progress?

A: The Xamarin ModuleLink Source Code for the ModuleLink application, can be downloaded from the product page of our SaBLE-x module, which also uses the ModuleLink application.
