We encountered a problem with this type of product. Chip emits a continuous wave signal at the carrier and does not react to external factors. Which leads to a complete stop testing products. In such cases, communication between other modules is not possible.
This problem does not bear a mass character. Caught about one in 50,000 - 100 million. The problem with software is excluded. It manifested in different types of products with different software. The total is only ss2510.
After switching on the chip, it works to the full battery discharge.
